Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565004, here are decompositions:

13 + 31564991 = 31565004
61 + 31564943 = 31565004
71 + 31564933 = 31565004
83 + 31564921 = 31565004
113 + 31564891 = 31565004
131 + 31564873 = 31565004
151 + 31564853 = 31565004
173 + 31564831 = 31565004

Showing the first eight; more decompositions exist.
