Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540002, here are decompositions:
- 31 + 31539971 = 31540002
- 71 + 31539931 = 31540002
- 101 + 31539901 = 31540002
- 113 + 31539889 = 31540002
- 139 + 31539863 = 31540002
- 163 + 31539839 = 31540002
- 181 + 31539821 = 31540002
- 239 + 31539763 = 31540002
Showing the first eight; more decompositions exist.
