Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534222, here are decompositions:

23 + 31534199 = 31534222
53 + 31534169 = 31534222
101 + 31534121 = 31534222
149 + 31534073 = 31534222
263 + 31533959 = 31534222
311 + 31533911 = 31534222
383 + 31533839 = 31534222
389 + 31533833 = 31534222

Showing the first eight; more decompositions exist.
