Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534018, here are decompositions:

59 + 31533959 = 31534018
107 + 31533911 = 31534018
179 + 31533839 = 31534018
227 + 31533791 = 31534018
311 + 31533707 = 31534018
359 + 31533659 = 31534018
419 + 31533599 = 31534018
431 + 31533587 = 31534018

Showing the first eight; more decompositions exist.
