Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143002, here are decompositions:
- 23 + 142979 = 143002
- 29 + 142973 = 143002
- 53 + 142949 = 143002
- 131 + 142871 = 143002
- 191 + 142811 = 143002
- 269 + 142733 = 143002
- 383 + 142619 = 143002
- 401 + 142601 = 143002
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 143,002 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 143002 first appears in π at position 538,825 of the decimal expansion (the 538,825ordinal-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.
