Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526490, here are decompositions:
- 13 + 31526477 = 31526490
- 59 + 31526431 = 31526490
- 67 + 31526423 = 31526490
- 71 + 31526419 = 31526490
- 101 + 31526389 = 31526490
- 103 + 31526387 = 31526490
- 131 + 31526359 = 31526490
- 139 + 31526351 = 31526490
Showing the first eight; more decompositions exist.
