Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589032, here are decompositions:

5 + 31589027 = 31589032
53 + 31588979 = 31589032
89 + 31588943 = 31589032
353 + 31588679 = 31589032
359 + 31588673 = 31589032
389 + 31588643 = 31589032
401 + 31588631 = 31589032
509 + 31588523 = 31589032

Showing the first eight; more decompositions exist.
