Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142304, here are decompositions:
- 7 + 142297 = 142304
- 67 + 142237 = 142304
- 73 + 142231 = 142304
- 181 + 142123 = 142304
- 193 + 142111 = 142304
- 313 + 141991 = 142304
- 367 + 141937 = 142304
- 373 + 141931 = 142304
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 142,304 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 142304 first appears in π at position 45,699 of the decimal expansion (the 45,699ordinal-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.
