Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028, here are decompositions:
- 7 + 1021 = 1028
- 19 + 1009 = 1028
- 31 + 997 = 1028
- 37 + 991 = 1028
- 61 + 967 = 1028
- 109 + 919 = 1028
- 151 + 877 = 1028
- 199 + 829 = 1028
Showing the first eight; more decompositions exist.

The digit sequence 1028 first appears in π at position 3,241 of the decimal expansion (the 3,241ordinal-suffix:st 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.
