Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589576, here are decompositions:

37 + 31589539 = 31589576
103 + 31589473 = 31589576
199 + 31589377 = 31589576
223 + 31589353 = 31589576
283 + 31589293 = 31589576
379 + 31589197 = 31589576
409 + 31589167 = 31589576
439 + 31589137 = 31589576

Showing the first eight; more decompositions exist.
