Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499634, here are decompositions:

13 + 31499621 = 31499634
41 + 31499593 = 31499634
73 + 31499561 = 31499634
97 + 31499537 = 31499634
137 + 31499497 = 31499634
167 + 31499467 = 31499634
223 + 31499411 = 31499634
227 + 31499407 = 31499634

Showing the first eight; more decompositions exist.
