Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598922, here are decompositions:

11 + 31598911 = 31598922
13 + 31598909 = 31598922
59 + 31598863 = 31598922
83 + 31598839 = 31598922
139 + 31598783 = 31598922
151 + 31598771 = 31598922
239 + 31598683 = 31598922
331 + 31598591 = 31598922

Showing the first eight; more decompositions exist.
