Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551614, here are decompositions:

37 + 31551577 = 31551614
67 + 31551547 = 31551614
97 + 31551517 = 31551614
163 + 31551451 = 31551614
307 + 31551307 = 31551614
331 + 31551283 = 31551614
337 + 31551277 = 31551614
463 + 31551151 = 31551614

Showing the first eight; more decompositions exist.
