Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489118, here are decompositions:
- 109 + 31489009 = 31489118
- 127 + 31488991 = 31489118
- 139 + 31488979 = 31489118
- 211 + 31488907 = 31489118
- 487 + 31488631 = 31489118
- 499 + 31488619 = 31489118
- 571 + 31488547 = 31489118
- 907 + 31488211 = 31489118
Showing the first eight; more decompositions exist.
