Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627512, here are decompositions:

11 + 31627501 = 31627512
29 + 31627483 = 31627512
101 + 31627411 = 31627512
139 + 31627373 = 31627512
179 + 31627333 = 31627512
193 + 31627319 = 31627512
223 + 31627289 = 31627512
251 + 31627261 = 31627512

Showing the first eight; more decompositions exist.
