Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627544, here are decompositions:

7 + 31627537 = 31627544
43 + 31627501 = 31627544
61 + 31627483 = 31627544
211 + 31627333 = 31627544
241 + 31627303 = 31627544
283 + 31627261 = 31627544
307 + 31627237 = 31627544
577 + 31626967 = 31627544

Showing the first eight; more decompositions exist.
