Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613004, here are decompositions:

13 + 31612991 = 31613004
23 + 31612981 = 31613004
43 + 31612961 = 31613004
53 + 31612951 = 31613004
113 + 31612891 = 31613004
131 + 31612873 = 31613004
151 + 31612853 = 31613004
173 + 31612831 = 31613004

Showing the first eight; more decompositions exist.
