Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541152, here are decompositions:
- 11 + 31541141 = 31541152
- 23 + 31541129 = 31541152
- 101 + 31541051 = 31541152
- 113 + 31541039 = 31541152
- 131 + 31541021 = 31541152
- 173 + 31540979 = 31541152
- 191 + 31540961 = 31541152
- 281 + 31540871 = 31541152
Showing the first eight; more decompositions exist.
