Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615016, here are decompositions:
- 3 + 31615013 = 31615016
- 73 + 31614943 = 31615016
- 127 + 31614889 = 31615016
- 157 + 31614859 = 31615016
- 163 + 31614853 = 31615016
- 229 + 31614787 = 31615016
- 283 + 31614733 = 31615016
- 313 + 31614703 = 31615016
Showing the first eight; more decompositions exist.
