Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541200, here are decompositions:
- 59 + 31541141 = 31541200
- 71 + 31541129 = 31541200
- 83 + 31541117 = 31541200
- 149 + 31541051 = 31541200
- 179 + 31541021 = 31541200
- 239 + 31540961 = 31541200
- 491 + 31540709 = 31541200
- 521 + 31540679 = 31541200
Showing the first eight; more decompositions exist.
