Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142704, here are decompositions:
- 5 + 142699 = 142704
- 7 + 142697 = 142704
- 31 + 142673 = 142704
- 47 + 142657 = 142704
- 97 + 142607 = 142704
- 103 + 142601 = 142704
- 113 + 142591 = 142704
- 131 + 142573 = 142704
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 142,704 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 142704 first appears in π at position 2,666 of the decimal expansion (the 2,666ordinal-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.
