Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627022, here are decompositions:

43 + 31626979 = 31627022
79 + 31626943 = 31627022
139 + 31626883 = 31627022
181 + 31626841 = 31627022
313 + 31626709 = 31627022
331 + 31626691 = 31627022
433 + 31626589 = 31627022
523 + 31626499 = 31627022

Showing the first eight; more decompositions exist.
