Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533946, here are decompositions:

23 + 31533923 = 31533946
107 + 31533839 = 31533946
113 + 31533833 = 31533946
173 + 31533773 = 31533946
239 + 31533707 = 31533946
347 + 31533599 = 31533946
359 + 31533587 = 31533946
383 + 31533563 = 31533946

Showing the first eight; more decompositions exist.
