Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499412, here are decompositions:

5 + 31499407 = 31499412
11 + 31499401 = 31499412
13 + 31499399 = 31499412
29 + 31499383 = 31499412
41 + 31499371 = 31499412
71 + 31499341 = 31499412
83 + 31499329 = 31499412
89 + 31499323 = 31499412

Showing the first eight; more decompositions exist.
