Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502066, here are decompositions:

109 + 31501957 = 31502066
307 + 31501759 = 31502066
367 + 31501699 = 31502066
397 + 31501669 = 31502066
433 + 31501633 = 31502066
499 + 31501567 = 31502066
619 + 31501447 = 31502066
733 + 31501333 = 31502066

Showing the first eight; more decompositions exist.
