Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501954, here are decompositions:

17 + 31501937 = 31501954
41 + 31501913 = 31501954
47 + 31501907 = 31501954
131 + 31501823 = 31501954
173 + 31501781 = 31501954
227 + 31501727 = 31501954
233 + 31501721 = 31501954
293 + 31501661 = 31501954

Showing the first eight; more decompositions exist.
