Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599922, here are decompositions:

5 + 31599917 = 31599922
113 + 31599809 = 31599922
149 + 31599773 = 31599922
239 + 31599683 = 31599922
251 + 31599671 = 31599922
269 + 31599653 = 31599922
293 + 31599629 = 31599922
311 + 31599611 = 31599922

Showing the first eight; more decompositions exist.
