Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499176, here are decompositions:

17 + 31499159 = 31499176
113 + 31499063 = 31499176
173 + 31499003 = 31499176
227 + 31498949 = 31499176
263 + 31498913 = 31499176
347 + 31498829 = 31499176
617 + 31498559 = 31499176
647 + 31498529 = 31499176

Showing the first eight; more decompositions exist.
