Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502534, here are decompositions:

103 + 31502431 = 31502534
163 + 31502371 = 31502534
181 + 31502353 = 31502534
223 + 31502311 = 31502534
373 + 31502161 = 31502534
421 + 31502113 = 31502534
577 + 31501957 = 31502534
673 + 31501861 = 31502534

Showing the first eight; more decompositions exist.
