Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627112, here are decompositions:

43 + 31627069 = 31627112
61 + 31627051 = 31627112
79 + 31627033 = 31627112
229 + 31626883 = 31627112
271 + 31626841 = 31627112
421 + 31626691 = 31627112
523 + 31626589 = 31627112
541 + 31626571 = 31627112

Showing the first eight; more decompositions exist.
