Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595004, here are decompositions:

5 + 31594999 = 31595004
13 + 31594991 = 31595004
17 + 31594987 = 31595004
41 + 31594963 = 31595004
43 + 31594961 = 31595004
73 + 31594931 = 31595004
97 + 31594907 = 31595004
101 + 31594903 = 31595004

Showing the first eight; more decompositions exist.
