Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499714, here are decompositions:

3 + 31499711 = 31499714
223 + 31499491 = 31499714
283 + 31499431 = 31499714
307 + 31499407 = 31499714
313 + 31499401 = 31499714
331 + 31499383 = 31499714
373 + 31499341 = 31499714
487 + 31499227 = 31499714

Showing the first eight; more decompositions exist.
