Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600490, here are decompositions:

37 + 31600453 = 31600490
43 + 31600447 = 31600490
67 + 31600423 = 31600490
157 + 31600333 = 31600490
199 + 31600291 = 31600490
211 + 31600279 = 31600490
373 + 31600117 = 31600490
433 + 31600057 = 31600490

Showing the first eight; more decompositions exist.
