Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486604, here are decompositions:

67 + 31486537 = 31486604
151 + 31486453 = 31486604
181 + 31486423 = 31486604
211 + 31486393 = 31486604
277 + 31486327 = 31486604
337 + 31486267 = 31486604
571 + 31486033 = 31486604
631 + 31485973 = 31486604

Showing the first eight; more decompositions exist.
