Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565504, here are decompositions:

7 + 31565497 = 31565504
13 + 31565491 = 31565504
31 + 31565473 = 31565504
43 + 31565461 = 31565504
67 + 31565437 = 31565504
73 + 31565431 = 31565504
127 + 31565377 = 31565504
151 + 31565353 = 31565504

Showing the first eight; more decompositions exist.
