Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626692, here are decompositions:

3 + 31626689 = 31626692
73 + 31626619 = 31626692
103 + 31626589 = 31626692
193 + 31626499 = 31626692
199 + 31626493 = 31626692
211 + 31626481 = 31626692
271 + 31626421 = 31626692
463 + 31626229 = 31626692

Showing the first eight; more decompositions exist.
