Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627142, here are decompositions:

73 + 31627069 = 31627142
109 + 31627033 = 31627142
163 + 31626979 = 31627142
199 + 31626943 = 31627142
433 + 31626709 = 31627142
523 + 31626619 = 31627142
571 + 31626571 = 31627142
643 + 31626499 = 31627142

Showing the first eight; more decompositions exist.
