Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626272, here are decompositions:

43 + 31626229 = 31626272
79 + 31626193 = 31626272
163 + 31626109 = 31626272
193 + 31626079 = 31626272
199 + 31626073 = 31626272
499 + 31625773 = 31626272
541 + 31625731 = 31626272
619 + 31625653 = 31626272

Showing the first eight; more decompositions exist.
