Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461626, here are decompositions:
- 73 + 31461553 = 31461626
- 103 + 31461523 = 31461626
- 109 + 31461517 = 31461626
- 139 + 31461487 = 31461626
- 199 + 31461427 = 31461626
- 223 + 31461403 = 31461626
- 277 + 31461349 = 31461626
- 283 + 31461343 = 31461626
Showing the first eight; more decompositions exist.
