Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534864, here are decompositions:
- 107 + 31534757 = 31534864
- 113 + 31534751 = 31534864
- 173 + 31534691 = 31534864
- 227 + 31534637 = 31534864
- 233 + 31534631 = 31534864
- 311 + 31534553 = 31534864
- 521 + 31534343 = 31534864
- 563 + 31534301 = 31534864
Showing the first eight; more decompositions exist.
