Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467472, here are decompositions:
- 5 + 31467467 = 31467472
- 41 + 31467431 = 31467472
- 53 + 31467419 = 31467472
- 83 + 31467389 = 31467472
- 269 + 31467203 = 31467472
- 383 + 31467089 = 31467472
- 389 + 31467083 = 31467472
- 401 + 31467071 = 31467472
Showing the first eight; more decompositions exist.
