Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142604, here are decompositions:
- 3 + 142601 = 142604
- 13 + 142591 = 142604
- 31 + 142573 = 142604
- 37 + 142567 = 142604
- 61 + 142543 = 142604
- 67 + 142537 = 142604
- 103 + 142501 = 142604
- 151 + 142453 = 142604
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 142,604 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 142604 first appears in π at position 193,542 of the decimal expansion (the 193,542ordinal-suffix:nd 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.
