Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539102, here are decompositions:
- 13 + 31539089 = 31539102
- 19 + 31539083 = 31539102
- 29 + 31539073 = 31539102
- 41 + 31539061 = 31539102
- 59 + 31539043 = 31539102
- 151 + 31538951 = 31539102
- 313 + 31538789 = 31539102
- 349 + 31538753 = 31539102
Showing the first eight; more decompositions exist.
