Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589164, here are decompositions:

107 + 31589057 = 31589164
137 + 31589027 = 31589164
317 + 31588847 = 31589164
491 + 31588673 = 31589164
521 + 31588643 = 31589164
557 + 31588607 = 31589164
641 + 31588523 = 31589164
701 + 31588463 = 31589164

Showing the first eight; more decompositions exist.
