Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589146, here are decompositions:

47 + 31589099 = 31589146
59 + 31589087 = 31589146
89 + 31589057 = 31589146
167 + 31588979 = 31589146
467 + 31588679 = 31589146
503 + 31588643 = 31589146
653 + 31588493 = 31589146
683 + 31588463 = 31589146

Showing the first eight; more decompositions exist.
