Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617772, here are decompositions:

59 + 31617713 = 31617772
83 + 31617689 = 31617772
113 + 31617659 = 31617772
239 + 31617533 = 31617772
269 + 31617503 = 31617772
311 + 31617461 = 31617772
359 + 31617413 = 31617772
401 + 31617371 = 31617772

Showing the first eight; more decompositions exist.
