Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559004, here are decompositions:

7 + 31558997 = 31559004
11 + 31558993 = 31559004
31 + 31558973 = 31559004
41 + 31558963 = 31559004
47 + 31558957 = 31559004
107 + 31558897 = 31559004
157 + 31558847 = 31559004
173 + 31558831 = 31559004

Showing the first eight; more decompositions exist.
