Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532556, here are decompositions:
- 5 + 31532551 = 31532556
- 17 + 31532539 = 31532556
- 59 + 31532497 = 31532556
- 67 + 31532489 = 31532556
- 79 + 31532477 = 31532556
- 127 + 31532429 = 31532556
- 227 + 31532329 = 31532556
- 233 + 31532323 = 31532556
Showing the first eight; more decompositions exist.
