Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607004, here are decompositions:

7 + 31606997 = 31607004
31 + 31606973 = 31607004
41 + 31606963 = 31607004
47 + 31606957 = 31607004
53 + 31606951 = 31607004
61 + 31606943 = 31607004
73 + 31606931 = 31607004
101 + 31606903 = 31607004

Showing the first eight; more decompositions exist.
