Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598836, here are decompositions:

47 + 31598789 = 31598836
53 + 31598783 = 31598836
83 + 31598753 = 31598836
149 + 31598687 = 31598836
167 + 31598669 = 31598836
293 + 31598543 = 31598836
317 + 31598519 = 31598836
419 + 31598417 = 31598836

Showing the first eight; more decompositions exist.
