Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454714, here are decompositions:

13 + 31454701 = 31454714
61 + 31454653 = 31454714
127 + 31454587 = 31454714
283 + 31454431 = 31454714
331 + 31454383 = 31454714
337 + 31454377 = 31454714
523 + 31454191 = 31454714
631 + 31454083 = 31454714

Showing the first eight; more decompositions exist.
