Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534228, here are decompositions:

29 + 31534199 = 31534228
41 + 31534187 = 31534228
59 + 31534169 = 31534228
107 + 31534121 = 31534228
149 + 31534079 = 31534228
269 + 31533959 = 31534228
317 + 31533911 = 31534228
389 + 31533839 = 31534228

Showing the first eight; more decompositions exist.
