Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486594, here are decompositions:

23 + 31486571 = 31486594
101 + 31486493 = 31486594
131 + 31486463 = 31486594
137 + 31486457 = 31486594
257 + 31486337 = 31486594
311 + 31486283 = 31486594
431 + 31486163 = 31486594
641 + 31485953 = 31486594

Showing the first eight; more decompositions exist.
