Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458516, here are decompositions:

29 + 31458487 = 31458516
79 + 31458437 = 31458516
97 + 31458419 = 31458516
113 + 31458403 = 31458516
137 + 31458379 = 31458516
139 + 31458377 = 31458516
239 + 31458277 = 31458516
277 + 31458239 = 31458516

Showing the first eight; more decompositions exist.
