Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541124, here are decompositions:
- 7 + 31541117 = 31541124
- 11 + 31541113 = 31541124
- 23 + 31541101 = 31541124
- 53 + 31541071 = 31541124
- 73 + 31541051 = 31541124
- 103 + 31541021 = 31541124
- 107 + 31541017 = 31541124
- 163 + 31540961 = 31541124
Showing the first eight; more decompositions exist.
