Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541028, here are decompositions:
- 7 + 31541021 = 31541028
- 11 + 31541017 = 31541028
- 37 + 31540991 = 31541028
- 67 + 31540961 = 31541028
- 89 + 31540939 = 31541028
- 107 + 31540921 = 31541028
- 157 + 31540871 = 31541028
- 191 + 31540837 = 31541028
Showing the first eight; more decompositions exist.
