Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600470, here are decompositions:

17 + 31600453 = 31600470
19 + 31600451 = 31600470
23 + 31600447 = 31600470
29 + 31600441 = 31600470
47 + 31600423 = 31600470
61 + 31600409 = 31600470
113 + 31600357 = 31600470
137 + 31600333 = 31600470

Showing the first eight; more decompositions exist.
