Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467744, here are decompositions:
- 17 + 31467727 = 31467744
- 23 + 31467721 = 31467744
- 53 + 31467691 = 31467744
- 67 + 31467677 = 31467744
- 97 + 31467647 = 31467744
- 151 + 31467593 = 31467744
- 157 + 31467587 = 31467744
- 173 + 31467571 = 31467744
Showing the first eight; more decompositions exist.
