Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539396, here are decompositions:
- 19 + 31539377 = 31539396
- 29 + 31539367 = 31539396
- 43 + 31539353 = 31539396
- 47 + 31539349 = 31539396
- 59 + 31539337 = 31539396
- 67 + 31539329 = 31539396
- 107 + 31539289 = 31539396
- 113 + 31539283 = 31539396
Showing the first eight; more decompositions exist.
