Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626572, here are decompositions:

73 + 31626499 = 31626572
79 + 31626493 = 31626572
151 + 31626421 = 31626572
379 + 31626193 = 31626572
463 + 31626109 = 31626572
499 + 31626073 = 31626572
619 + 31625953 = 31626572
661 + 31625911 = 31626572

Showing the first eight; more decompositions exist.
