Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486364, here are decompositions:

37 + 31486327 = 31486364
61 + 31486303 = 31486364
97 + 31486267 = 31486364
163 + 31486201 = 31486364
241 + 31486123 = 31486364
277 + 31486087 = 31486364
331 + 31486033 = 31486364
433 + 31485931 = 31486364

Showing the first eight; more decompositions exist.
