Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530504, here are decompositions:

7 + 31530497 = 31530504
17 + 31530487 = 31530504
53 + 31530451 = 31530504
67 + 31530437 = 31530504
113 + 31530391 = 31530504
127 + 31530377 = 31530504
157 + 31530347 = 31530504
163 + 31530341 = 31530504

Showing the first eight; more decompositions exist.
