Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613040, here are decompositions:
- 13 + 31613027 = 31613040
- 59 + 31612981 = 31613040
- 71 + 31612969 = 31613040
- 79 + 31612961 = 31613040
- 89 + 31612951 = 31613040
- 101 + 31612939 = 31613040
- 127 + 31612913 = 31613040
- 149 + 31612891 = 31613040
Showing the first eight; more decompositions exist.
