Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142504, here are decompositions:
- 3 + 142501 = 142504
- 71 + 142433 = 142504
- 83 + 142421 = 142504
- 101 + 142403 = 142504
- 113 + 142391 = 142504
- 233 + 142271 = 142504
- 281 + 142223 = 142504
- 293 + 142211 = 142504
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 142,504 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 142504 first appears in π at position 175,128 of the decimal expansion (the 175,128ordinal-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.
