Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528712, here are decompositions:
- 43 + 31528669 = 31528712
- 79 + 31528633 = 31528712
- 139 + 31528573 = 31528712
- 181 + 31528531 = 31528712
- 211 + 31528501 = 31528712
- 349 + 31528363 = 31528712
- 421 + 31528291 = 31528712
- 433 + 31528279 = 31528712
Showing the first eight; more decompositions exist.
