Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517004, here are decompositions:

11 + 31516993 = 31517004
23 + 31516981 = 31517004
31 + 31516973 = 31517004
53 + 31516951 = 31517004
163 + 31516841 = 31517004
193 + 31516811 = 31517004
223 + 31516781 = 31517004
227 + 31516777 = 31517004

Showing the first eight; more decompositions exist.
