Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567922, here are decompositions:

73 + 31567849 = 31567922
103 + 31567819 = 31567922
109 + 31567813 = 31567922
181 + 31567741 = 31567922
193 + 31567729 = 31567922
223 + 31567699 = 31567922
229 + 31567693 = 31567922
241 + 31567681 = 31567922

Showing the first eight; more decompositions exist.
