Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534518, here are decompositions:

17 + 31534501 = 31534518
31 + 31534487 = 31534518
61 + 31534457 = 31534518
89 + 31534429 = 31534518
107 + 31534411 = 31534518
149 + 31534369 = 31534518
271 + 31534247 = 31534518
277 + 31534241 = 31534518

Showing the first eight; more decompositions exist.
