Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601950, here are decompositions:

53 + 31601897 = 31601950
59 + 31601891 = 31601950
101 + 31601849 = 31601950
113 + 31601837 = 31601950
131 + 31601819 = 31601950
167 + 31601783 = 31601950
227 + 31601723 = 31601950
239 + 31601711 = 31601950

Showing the first eight; more decompositions exist.
