Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627366, here are decompositions:

47 + 31627319 = 31627366
149 + 31627217 = 31627366
233 + 31627133 = 31627366
293 + 31627073 = 31627366
359 + 31627007 = 31627366
389 + 31626977 = 31627366
467 + 31626899 = 31627366
509 + 31626857 = 31627366

Showing the first eight; more decompositions exist.
