Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502456, here are decompositions:

103 + 31502353 = 31502456
127 + 31502329 = 31502456
373 + 31502083 = 31502456
499 + 31501957 = 31502456
577 + 31501879 = 31502456
607 + 31501849 = 31502456
757 + 31501699 = 31502456
787 + 31501669 = 31502456

Showing the first eight; more decompositions exist.
