Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499382, here are decompositions:

11 + 31499371 = 31499382
41 + 31499341 = 31499382
53 + 31499329 = 31499382
59 + 31499323 = 31499382
71 + 31499311 = 31499382
73 + 31499309 = 31499382
151 + 31499231 = 31499382
193 + 31499189 = 31499382

Showing the first eight; more decompositions exist.
