Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142684, here are decompositions:
- 11 + 142673 = 142684
- 83 + 142601 = 142684
- 131 + 142553 = 142684
- 137 + 142547 = 142684
- 251 + 142433 = 142684
- 257 + 142427 = 142684
- 263 + 142421 = 142684
- 281 + 142403 = 142684
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 142,684 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 142684 first appears in π at position 123,559 of the decimal expansion (the 123,559ordinal-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.
