Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513104, here are decompositions:
- 13 + 31513091 = 31513104
- 31 + 31513073 = 31513104
- 41 + 31513063 = 31513104
- 47 + 31513057 = 31513104
- 67 + 31513037 = 31513104
- 71 + 31513033 = 31513104
- 97 + 31513007 = 31513104
- 101 + 31513003 = 31513104
Showing the first eight; more decompositions exist.
