Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142750, here are decompositions:
- 17 + 142733 = 142750
- 53 + 142697 = 142750
- 131 + 142619 = 142750
- 149 + 142601 = 142750
- 191 + 142559 = 142750
- 197 + 142553 = 142750
- 281 + 142469 = 142750
- 317 + 142433 = 142750
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 142,750 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 142750 first appears in π at position 806,246 of the decimal expansion (the 806,246ordinal-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.
