Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608794, here are decompositions:

37 + 31608757 = 31608794
67 + 31608727 = 31608794
73 + 31608721 = 31608794
97 + 31608697 = 31608794
127 + 31608667 = 31608794
313 + 31608481 = 31608794
367 + 31608427 = 31608794
457 + 31608337 = 31608794

Showing the first eight; more decompositions exist.
