Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142804, here are decompositions:
- 5 + 142799 = 142804
- 17 + 142787 = 142804
- 47 + 142757 = 142804
- 71 + 142733 = 142804
- 107 + 142697 = 142804
- 131 + 142673 = 142804
- 197 + 142607 = 142804
- 251 + 142553 = 142804
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 142,804 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 142804 first appears in π at position 237,072 of the decimal expansion (the 237,072ordinal-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.
