Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470950, here are decompositions:

37 + 31470913 = 31470950
61 + 31470889 = 31470950
97 + 31470853 = 31470950
103 + 31470847 = 31470950
127 + 31470823 = 31470950
151 + 31470799 = 31470950
157 + 31470793 = 31470950
163 + 31470787 = 31470950

Showing the first eight; more decompositions exist.
