Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626206, here are decompositions:

13 + 31626193 = 31626206
97 + 31626109 = 31626206
127 + 31626079 = 31626206
433 + 31625773 = 31626206
439 + 31625767 = 31626206
607 + 31625599 = 31626206
643 + 31625563 = 31626206
739 + 31625467 = 31626206

Showing the first eight; more decompositions exist.
