Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627306, here are decompositions:

3 + 31627303 = 31627306
17 + 31627289 = 31627306
59 + 31627247 = 31627306
89 + 31627217 = 31627306
173 + 31627133 = 31627306
233 + 31627073 = 31627306
449 + 31626857 = 31627306
467 + 31626839 = 31627306

Showing the first eight; more decompositions exist.
