Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541230, here are decompositions:
- 89 + 31541141 = 31541230
- 101 + 31541129 = 31541230
- 113 + 31541117 = 31541230
- 179 + 31541051 = 31541230
- 191 + 31541039 = 31541230
- 239 + 31540991 = 31541230
- 251 + 31540979 = 31541230
- 269 + 31540961 = 31541230
Showing the first eight; more decompositions exist.
