Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541118, here are decompositions:
- 5 + 31541113 = 31541118
- 17 + 31541101 = 31541118
- 47 + 31541071 = 31541118
- 67 + 31541051 = 31541118
- 71 + 31541047 = 31541118
- 79 + 31541039 = 31541118
- 97 + 31541021 = 31541118
- 101 + 31541017 = 31541118
Showing the first eight; more decompositions exist.
