Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451004, here are decompositions:
- 7 + 31450997 = 31451004
- 37 + 31450967 = 31451004
- 43 + 31450961 = 31451004
- 107 + 31450897 = 31451004
- 113 + 31450891 = 31451004
- 157 + 31450847 = 31451004
- 163 + 31450841 = 31451004
- 181 + 31450823 = 31451004
Showing the first eight; more decompositions exist.
