Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1982, here are decompositions:
- 3 + 1979 = 1982
- 31 + 1951 = 1982
- 103 + 1879 = 1982
- 109 + 1873 = 1982
- 151 + 1831 = 1982
- 181 + 1801 = 1982
- 193 + 1789 = 1982
- 199 + 1783 = 1982
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.0.7.190.

The digit sequence 1982 first appears in π at position 23,887 of the decimal expansion (the 23,887ordinal-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.
