Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542424, here are decompositions:
- 5 + 31542419 = 31542424
- 47 + 31542377 = 31542424
- 83 + 31542341 = 31542424
- 101 + 31542323 = 31542424
- 191 + 31542233 = 31542424
- 227 + 31542197 = 31542424
- 311 + 31542113 = 31542424
- 401 + 31542023 = 31542424
Showing the first eight; more decompositions exist.
