Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528036, here are decompositions:

17 + 31528019 = 31528036
149 + 31527887 = 31528036
347 + 31527689 = 31528036
359 + 31527677 = 31528036
467 + 31527569 = 31528036
503 + 31527533 = 31528036
647 + 31527389 = 31528036
719 + 31527317 = 31528036

Showing the first eight; more decompositions exist.
