Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589944, here are decompositions:

53 + 31589891 = 31589944
83 + 31589861 = 31589944
101 + 31589843 = 31589944
167 + 31589777 = 31589944
173 + 31589771 = 31589944
233 + 31589711 = 31589944
251 + 31589693 = 31589944
311 + 31589633 = 31589944

Showing the first eight; more decompositions exist.
