Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627524, here are decompositions:

13 + 31627511 = 31627524
23 + 31627501 = 31627524
41 + 31627483 = 31627524
113 + 31627411 = 31627524
151 + 31627373 = 31627524
167 + 31627357 = 31627524
191 + 31627333 = 31627524
263 + 31627261 = 31627524

Showing the first eight; more decompositions exist.
