Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514570, here are decompositions:

19 + 31514551 = 31514570
37 + 31514533 = 31514570
97 + 31514473 = 31514570
151 + 31514419 = 31514570
331 + 31514239 = 31514570
349 + 31514221 = 31514570
379 + 31514191 = 31514570
421 + 31514149 = 31514570

Showing the first eight; more decompositions exist.
