Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502046, here are decompositions:

67 + 31501979 = 31502046
89 + 31501957 = 31502046
109 + 31501937 = 31502046
139 + 31501907 = 31502046
167 + 31501879 = 31502046
197 + 31501849 = 31502046
223 + 31501823 = 31502046
227 + 31501819 = 31502046

Showing the first eight; more decompositions exist.
