Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589002, here are decompositions:

23 + 31588979 = 31589002
59 + 31588943 = 31589002
293 + 31588709 = 31589002
359 + 31588643 = 31589002
479 + 31588523 = 31589002
509 + 31588493 = 31589002
563 + 31588439 = 31589002
941 + 31588061 = 31589002

Showing the first eight; more decompositions exist.
