Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502804, here are decompositions:

43 + 31502761 = 31502804
61 + 31502743 = 31502804
103 + 31502701 = 31502804
241 + 31502563 = 31502804
271 + 31502533 = 31502804
373 + 31502431 = 31502804
433 + 31502371 = 31502804
643 + 31502161 = 31502804

Showing the first eight; more decompositions exist.
