Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486316, here are decompositions:

13 + 31486303 = 31486316
193 + 31486123 = 31486316
229 + 31486087 = 31486316
283 + 31486033 = 31486316
307 + 31486009 = 31486316
733 + 31485583 = 31486316
919 + 31485397 = 31486316
937 + 31485379 = 31486316

Showing the first eight; more decompositions exist.
