Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502074, here are decompositions:

137 + 31501937 = 31502074
167 + 31501907 = 31502074
251 + 31501823 = 31502074
293 + 31501781 = 31502074
347 + 31501727 = 31502074
353 + 31501721 = 31502074
491 + 31501583 = 31502074
641 + 31501433 = 31502074

Showing the first eight; more decompositions exist.
