Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527982, here are decompositions:

41 + 31527941 = 31527982
281 + 31527701 = 31527982
293 + 31527689 = 31527982
449 + 31527533 = 31527982
461 + 31527521 = 31527982
491 + 31527491 = 31527982
569 + 31527413 = 31527982
593 + 31527389 = 31527982

Showing the first eight; more decompositions exist.
