Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486504, here are decompositions:

11 + 31486493 = 31486504
41 + 31486463 = 31486504
47 + 31486457 = 31486504
53 + 31486451 = 31486504
113 + 31486391 = 31486504
167 + 31486337 = 31486504
197 + 31486307 = 31486504
233 + 31486271 = 31486504

Showing the first eight; more decompositions exist.
