Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600650, here are decompositions:

31 + 31600619 = 31600650
101 + 31600549 = 31600650
127 + 31600523 = 31600650
139 + 31600511 = 31600650
157 + 31600493 = 31600650
197 + 31600453 = 31600650
199 + 31600451 = 31600650
227 + 31600423 = 31600650

Showing the first eight; more decompositions exist.
