Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142658, here are decompositions:
- 67 + 142591 = 142658
- 157 + 142501 = 142658
- 277 + 142381 = 142658
- 331 + 142327 = 142658
- 421 + 142237 = 142658
- 499 + 142159 = 142658
- 547 + 142111 = 142658
- 601 + 142057 = 142658
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 142,658 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 142658 first appears in π at position 423,496 of the decimal expansion (the 423,496ordinal-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.
