Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590076, here are decompositions:

5 + 31590071 = 31590076
233 + 31589843 = 31590076
257 + 31589819 = 31590076
317 + 31589759 = 31590076
383 + 31589693 = 31590076
443 + 31589633 = 31590076
509 + 31589567 = 31590076
563 + 31589513 = 31590076

Showing the first eight; more decompositions exist.
