Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627612, here are decompositions:

11 + 31627601 = 31627612
53 + 31627559 = 31627612
101 + 31627511 = 31627612
239 + 31627373 = 31627612
293 + 31627319 = 31627612
461 + 31627151 = 31627612
479 + 31627133 = 31627612
491 + 31627121 = 31627612

Showing the first eight; more decompositions exist.
