Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485634, here are decompositions:

23 + 31485611 = 31485634
101 + 31485533 = 31485634
137 + 31485497 = 31485634
227 + 31485407 = 31485634
233 + 31485401 = 31485634
251 + 31485383 = 31485634
281 + 31485353 = 31485634
293 + 31485341 = 31485634

Showing the first eight; more decompositions exist.
