Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499508, here are decompositions:

11 + 31499497 = 31499508
17 + 31499491 = 31499508
41 + 31499467 = 31499508
97 + 31499411 = 31499508
101 + 31499407 = 31499508
107 + 31499401 = 31499508
109 + 31499399 = 31499508
137 + 31499371 = 31499508

Showing the first eight; more decompositions exist.
