Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589608, here are decompositions:

41 + 31589567 = 31589608
47 + 31589561 = 31589608
269 + 31589339 = 31589608
311 + 31589297 = 31589608
317 + 31589291 = 31589608
509 + 31589099 = 31589608
521 + 31589087 = 31589608
761 + 31588847 = 31589608

Showing the first eight; more decompositions exist.
