Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541040, here are decompositions:
- 19 + 31541021 = 31541040
- 23 + 31541017 = 31541040
- 61 + 31540979 = 31541040
- 79 + 31540961 = 31541040
- 101 + 31540939 = 31541040
- 173 + 31540867 = 31541040
- 227 + 31540813 = 31541040
- 257 + 31540783 = 31541040
Showing the first eight; more decompositions exist.
