Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506022, here are decompositions:

29 + 31505993 = 31506022
83 + 31505939 = 31506022
101 + 31505921 = 31506022
113 + 31505909 = 31506022
179 + 31505843 = 31506022
239 + 31505783 = 31506022
281 + 31505741 = 31506022
293 + 31505729 = 31506022

Showing the first eight; more decompositions exist.
