Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588316, here are decompositions:
- 3 + 31588313 = 31588316
- 13 + 31588303 = 31588316
- 229 + 31588087 = 31588316
- 313 + 31588003 = 31588316
- 337 + 31587979 = 31588316
- 367 + 31587949 = 31588316
- 373 + 31587943 = 31588316
- 439 + 31587877 = 31588316
Showing the first eight; more decompositions exist.
