Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467818, here are decompositions:
- 7 + 31467811 = 31467818
- 97 + 31467721 = 31467818
- 127 + 31467691 = 31467818
- 229 + 31467589 = 31467818
- 337 + 31467481 = 31467818
- 619 + 31467199 = 31467818
- 661 + 31467157 = 31467818
- 691 + 31467127 = 31467818
Showing the first eight; more decompositions exist.
