Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502504, here are decompositions:

73 + 31502431 = 31502504
151 + 31502353 = 31502504
193 + 31502311 = 31502504
373 + 31502131 = 31502504
421 + 31502083 = 31502504
547 + 31501957 = 31502504
643 + 31501861 = 31502504
673 + 31501831 = 31502504

Showing the first eight; more decompositions exist.
