Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501924, here are decompositions:

11 + 31501913 = 31501924
17 + 31501907 = 31501924
101 + 31501823 = 31501924
173 + 31501751 = 31501924
197 + 31501727 = 31501924
263 + 31501661 = 31501924
401 + 31501523 = 31501924
491 + 31501433 = 31501924

Showing the first eight; more decompositions exist.
