Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030, here are decompositions:
- 11 + 1019 = 1030
- 17 + 1013 = 1030
- 47 + 983 = 1030
- 53 + 977 = 1030
- 59 + 971 = 1030
- 83 + 947 = 1030
- 89 + 941 = 1030
- 101 + 929 = 1030
Showing the first eight; more decompositions exist.

The digit sequence 1030 first appears in π at position 20,818 of the decimal expansion (the 20,818ordinal-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.
