Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626762, here are decompositions:

53 + 31626709 = 31626762
71 + 31626691 = 31626762
73 + 31626689 = 31626762
173 + 31626589 = 31626762
191 + 31626571 = 31626762
199 + 31626563 = 31626762
229 + 31626533 = 31626762
263 + 31626499 = 31626762

Showing the first eight; more decompositions exist.
