Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600488, here are decompositions:

37 + 31600451 = 31600488
41 + 31600447 = 31600488
47 + 31600441 = 31600488
67 + 31600421 = 31600488
79 + 31600409 = 31600488
131 + 31600357 = 31600488
181 + 31600307 = 31600488
197 + 31600291 = 31600488

Showing the first eight; more decompositions exist.
