Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589974, here are decompositions:

83 + 31589891 = 31589974
107 + 31589867 = 31589974
113 + 31589861 = 31589974
131 + 31589843 = 31589974
197 + 31589777 = 31589974
263 + 31589711 = 31589974
281 + 31589693 = 31589974
461 + 31589513 = 31589974

Showing the first eight; more decompositions exist.
