Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499496, here are decompositions:

5 + 31499491 = 31499496
29 + 31499467 = 31499496
37 + 31499459 = 31499496
89 + 31499407 = 31499496
97 + 31499399 = 31499496
109 + 31499387 = 31499496
113 + 31499383 = 31499496
167 + 31499329 = 31499496

Showing the first eight; more decompositions exist.
