Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598986, here are decompositions:

47 + 31598939 = 31598986
53 + 31598933 = 31598986
59 + 31598927 = 31598986
113 + 31598873 = 31598986
197 + 31598789 = 31598986
233 + 31598753 = 31598986
269 + 31598717 = 31598986
317 + 31598669 = 31598986

Showing the first eight; more decompositions exist.
