Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626230, here are decompositions:

37 + 31626193 = 31626230
151 + 31626079 = 31626230
157 + 31626073 = 31626230
211 + 31626019 = 31626230
277 + 31625953 = 31626230
313 + 31625917 = 31626230
409 + 31625821 = 31626230
457 + 31625773 = 31626230

Showing the first eight; more decompositions exist.
