Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589938, here are decompositions:

47 + 31589891 = 31589938
71 + 31589867 = 31589938
167 + 31589771 = 31589938
179 + 31589759 = 31589938
227 + 31589711 = 31589938
599 + 31589339 = 31589938
617 + 31589321 = 31589938
641 + 31589297 = 31589938

Showing the first eight; more decompositions exist.
