Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514858, here are decompositions:

19 + 31514839 = 31514858
127 + 31514731 = 31514858
229 + 31514629 = 31514858
307 + 31514551 = 31514858
379 + 31514479 = 31514858
409 + 31514449 = 31514858
439 + 31514419 = 31514858
457 + 31514401 = 31514858

Showing the first eight; more decompositions exist.
