Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626688, here are decompositions:

131 + 31626557 = 31626688
227 + 31626461 = 31626688
251 + 31626437 = 31626688
281 + 31626407 = 31626688
311 + 31626377 = 31626688
479 + 31626209 = 31626688
491 + 31626197 = 31626688
521 + 31626167 = 31626688

Showing the first eight; more decompositions exist.
