Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142984, here are decompositions:
- 3 + 142981 = 142984
- 5 + 142979 = 142984
- 11 + 142973 = 142984
- 113 + 142871 = 142984
- 173 + 142811 = 142984
- 197 + 142787 = 142984
- 227 + 142757 = 142984
- 251 + 142733 = 142984
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 142,984 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 142984 first appears in π at position 565,330 of the decimal expansion (the 565,330ordinal-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.
