Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626514, here are decompositions:

53 + 31626461 = 31626514
107 + 31626407 = 31626514
131 + 31626383 = 31626514
137 + 31626377 = 31626514
191 + 31626323 = 31626514
281 + 31626233 = 31626514
317 + 31626197 = 31626514
347 + 31626167 = 31626514

Showing the first eight; more decompositions exist.
