Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589044, here are decompositions:

17 + 31589027 = 31589044
101 + 31588943 = 31589044
197 + 31588847 = 31589044
401 + 31588643 = 31589044
521 + 31588523 = 31589044
677 + 31588367 = 31589044
797 + 31588247 = 31589044
887 + 31588157 = 31589044

Showing the first eight; more decompositions exist.
