Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508016, here are decompositions:
- 13 + 31508003 = 31508016
- 103 + 31507913 = 31508016
- 139 + 31507877 = 31508016
- 179 + 31507837 = 31508016
- 193 + 31507823 = 31508016
- 223 + 31507793 = 31508016
- 227 + 31507789 = 31508016
- 229 + 31507787 = 31508016
Showing the first eight; more decompositions exist.
