Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619466, here are decompositions:

7 + 31619459 = 31619466
59 + 31619407 = 31619466
79 + 31619387 = 31619466
107 + 31619359 = 31619466
139 + 31619327 = 31619466
199 + 31619267 = 31619466
257 + 31619209 = 31619466
283 + 31619183 = 31619466

Showing the first eight; more decompositions exist.
