Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627564, here are decompositions:

5 + 31627559 = 31627564
53 + 31627511 = 31627564
173 + 31627391 = 31627564
191 + 31627373 = 31627564
317 + 31627247 = 31627564
347 + 31627217 = 31627564
431 + 31627133 = 31627564
443 + 31627121 = 31627564

Showing the first eight; more decompositions exist.
