Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617934, here are decompositions:

71 + 31617863 = 31617934
107 + 31617827 = 31617934
137 + 31617797 = 31617934
347 + 31617587 = 31617934
401 + 31617533 = 31617934
431 + 31617503 = 31617934
503 + 31617431 = 31617934
521 + 31617413 = 31617934

Showing the first eight; more decompositions exist.
