Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627602, here are decompositions:

29 + 31627573 = 31627602
43 + 31627559 = 31627602
59 + 31627543 = 31627602
101 + 31627501 = 31627602
191 + 31627411 = 31627602
211 + 31627391 = 31627602
229 + 31627373 = 31627602
269 + 31627333 = 31627602

Showing the first eight; more decompositions exist.
