Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499468, here are decompositions:

37 + 31499431 = 31499468
61 + 31499407 = 31499468
67 + 31499401 = 31499468
97 + 31499371 = 31499468
127 + 31499341 = 31499468
139 + 31499329 = 31499468
157 + 31499311 = 31499468
229 + 31499239 = 31499468

Showing the first eight; more decompositions exist.
