Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484836, here are decompositions:

59 + 31484777 = 31484836
83 + 31484753 = 31484836
137 + 31484699 = 31484836
293 + 31484543 = 31484836
419 + 31484417 = 31484836
569 + 31484267 = 31484836
599 + 31484237 = 31484836
659 + 31484177 = 31484836

Showing the first eight; more decompositions exist.
