Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589838, here are decompositions:

11 + 31589827 = 31589838
19 + 31589819 = 31589838
61 + 31589777 = 31589838
67 + 31589771 = 31589838
79 + 31589759 = 31589838
101 + 31589737 = 31589838
107 + 31589731 = 31589838
127 + 31589711 = 31589838

Showing the first eight; more decompositions exist.
