Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499814, here are decompositions:

11 + 31499803 = 31499814
53 + 31499761 = 31499814
83 + 31499731 = 31499814
103 + 31499711 = 31499814
193 + 31499621 = 31499814
277 + 31499537 = 31499814
317 + 31499497 = 31499814
347 + 31499467 = 31499814

Showing the first eight; more decompositions exist.
