Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588442, here are decompositions:
- 3 + 31588439 = 31588442
- 43 + 31588399 = 31588442
- 73 + 31588369 = 31588442
- 139 + 31588303 = 31588442
- 241 + 31588201 = 31588442
- 271 + 31588171 = 31588442
- 313 + 31588129 = 31588442
- 439 + 31588003 = 31588442
Showing the first eight; more decompositions exist.
