Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499448, here are decompositions:

17 + 31499431 = 31499448
37 + 31499411 = 31499448
41 + 31499407 = 31499448
47 + 31499401 = 31499448
61 + 31499387 = 31499448
107 + 31499341 = 31499448
137 + 31499311 = 31499448
139 + 31499309 = 31499448

Showing the first eight; more decompositions exist.
