Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515934, here are decompositions:
- 3 + 31515931 = 31515934
- 41 + 31515893 = 31515934
- 53 + 31515881 = 31515934
- 113 + 31515821 = 31515934
- 167 + 31515767 = 31515934
- 251 + 31515683 = 31515934
- 257 + 31515677 = 31515934
- 293 + 31515641 = 31515934
Showing the first eight; more decompositions exist.
