Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541064, here are decompositions:
- 13 + 31541051 = 31541064
- 17 + 31541047 = 31541064
- 43 + 31541021 = 31541064
- 47 + 31541017 = 31541064
- 73 + 31540991 = 31541064
- 103 + 31540961 = 31541064
- 193 + 31540871 = 31541064
- 197 + 31540867 = 31541064
Showing the first eight; more decompositions exist.
