Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600464, here are decompositions:

11 + 31600453 = 31600464
13 + 31600451 = 31600464
17 + 31600447 = 31600464
23 + 31600441 = 31600464
41 + 31600423 = 31600464
43 + 31600421 = 31600464
107 + 31600357 = 31600464
131 + 31600333 = 31600464

Showing the first eight; more decompositions exist.
