Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142936, here are decompositions:
- 29 + 142907 = 142936
- 137 + 142799 = 142936
- 149 + 142787 = 142936
- 179 + 142757 = 142936
- 239 + 142697 = 142936
- 263 + 142673 = 142936
- 317 + 142619 = 142936
- 347 + 142589 = 142936
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,936 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 142936 first appears in π at position 823,954 of the decimal expansion (the 823,954ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
