Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619214, here are decompositions:

5 + 31619209 = 31619214
7 + 31619207 = 31619214
23 + 31619191 = 31619214
31 + 31619183 = 31619214
37 + 31619177 = 31619214
43 + 31619171 = 31619214
71 + 31619143 = 31619214
97 + 31619117 = 31619214

Showing the first eight; more decompositions exist.
