Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523922, here are decompositions:

5 + 31523917 = 31523922
41 + 31523881 = 31523922
71 + 31523851 = 31523922
83 + 31523839 = 31523922
173 + 31523749 = 31523922
263 + 31523659 = 31523922
271 + 31523651 = 31523922
383 + 31523539 = 31523922

Showing the first eight; more decompositions exist.
