Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626470, here are decompositions:

103 + 31626367 = 31626470
223 + 31626247 = 31626470
241 + 31626229 = 31626470
277 + 31626193 = 31626470
397 + 31626073 = 31626470
691 + 31625779 = 31626470
709 + 31625761 = 31626470
739 + 31625731 = 31626470

Showing the first eight; more decompositions exist.
