Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499196, here are decompositions:
- 7 + 31499189 = 31499196
- 13 + 31499183 = 31499196
- 37 + 31499159 = 31499196
- 59 + 31499137 = 31499196
- 89 + 31499107 = 31499196
- 139 + 31499057 = 31499196
- 163 + 31499033 = 31499196
- 173 + 31499023 = 31499196
Showing the first eight; more decompositions exist.
