Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600494, here are decompositions:

41 + 31600453 = 31600494
43 + 31600451 = 31600494
47 + 31600447 = 31600494
53 + 31600441 = 31600494
71 + 31600423 = 31600494
73 + 31600421 = 31600494
137 + 31600357 = 31600494
193 + 31600301 = 31600494

Showing the first eight; more decompositions exist.
