Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1072, here are decompositions:
- 3 + 1069 = 1072
- 11 + 1061 = 1072
- 23 + 1049 = 1072
- 41 + 1031 = 1072
- 53 + 1019 = 1072
- 59 + 1013 = 1072
- 89 + 983 = 1072
- 101 + 971 = 1072
Showing the first eight; more decompositions exist.

The digit sequence 1072 first appears in π at position 8,419 of the decimal expansion (the 8,419ordinal-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.
