Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1200, here are decompositions:
- 7 + 1193 = 1200
- 13 + 1187 = 1200
- 19 + 1181 = 1200
- 29 + 1171 = 1200
- 37 + 1163 = 1200
- 47 + 1153 = 1200
- 71 + 1129 = 1200
- 83 + 1117 = 1200
Showing the first eight; more decompositions exist.

The digit sequence 1200 first appears in π at position 8,622 of the decimal expansion (the 8,622ordinal-suffix:nd 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.
