Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599082, here are decompositions:

23 + 31599059 = 31599082
149 + 31598933 = 31599082
173 + 31598909 = 31599082
293 + 31598789 = 31599082
311 + 31598771 = 31599082
491 + 31598591 = 31599082
563 + 31598519 = 31599082
569 + 31598513 = 31599082

Showing the first eight; more decompositions exist.
