Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588382, here are decompositions:
- 13 + 31588369 = 31588382
- 31 + 31588351 = 31588382
- 61 + 31588321 = 31588382
- 79 + 31588303 = 31588382
- 181 + 31588201 = 31588382
- 211 + 31588171 = 31588382
- 379 + 31588003 = 31588382
- 421 + 31587961 = 31588382
Showing the first eight; more decompositions exist.
