Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541010, here are decompositions:
- 19 + 31540991 = 31541010
- 31 + 31540979 = 31541010
- 71 + 31540939 = 31541010
- 89 + 31540921 = 31541010
- 139 + 31540871 = 31541010
- 173 + 31540837 = 31541010
- 197 + 31540813 = 31541010
- 223 + 31540787 = 31541010
Showing the first eight; more decompositions exist.
