Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627550, here are decompositions:

7 + 31627543 = 31627550
13 + 31627537 = 31627550
67 + 31627483 = 31627550
139 + 31627411 = 31627550
193 + 31627357 = 31627550
307 + 31627243 = 31627550
313 + 31627237 = 31627550
349 + 31627201 = 31627550

Showing the first eight; more decompositions exist.
