Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589212, here are decompositions:

29 + 31589183 = 31589212
113 + 31589099 = 31589212
233 + 31588979 = 31589212
269 + 31588943 = 31589212
503 + 31588709 = 31589212
569 + 31588643 = 31589212
719 + 31588493 = 31589212
773 + 31588439 = 31589212

Showing the first eight; more decompositions exist.
