Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584336, here are decompositions:
- 13 + 31584323 = 31584336
- 29 + 31584307 = 31584336
- 37 + 31584299 = 31584336
- 73 + 31584263 = 31584336
- 89 + 31584247 = 31584336
- 103 + 31584233 = 31584336
- 139 + 31584197 = 31584336
- 163 + 31584173 = 31584336
Showing the first eight; more decompositions exist.
