Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528116, here are decompositions:
- 5 + 31528111 = 31528116
- 13 + 31528103 = 31528116
- 23 + 31528093 = 31528116
- 47 + 31528069 = 31528116
- 79 + 31528037 = 31528116
- 97 + 31528019 = 31528116
- 149 + 31527967 = 31528116
- 229 + 31527887 = 31528116
Showing the first eight; more decompositions exist.
