Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742224, here are decompositions:

31 + 8742193 = 8742224
37 + 8742187 = 8742224
67 + 8742157 = 8742224
103 + 8742121 = 8742224
157 + 8742067 = 8742224
241 + 8741983 = 8742224
277 + 8741947 = 8742224
313 + 8741911 = 8742224

Showing the first eight; more decompositions exist.
