Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582036, here are decompositions:

53 + 31581983 = 31582036
89 + 31581947 = 31582036
173 + 31581863 = 31582036
257 + 31581779 = 31582036
359 + 31581677 = 31582036
419 + 31581617 = 31582036
467 + 31581569 = 31582036
587 + 31581449 = 31582036

Showing the first eight; more decompositions exist.
