Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742312, here are decompositions:

53 + 8742259 = 8742312
151 + 8742161 = 8742312
179 + 8742133 = 8742312
191 + 8742121 = 8742312
379 + 8741933 = 8742312
389 + 8741923 = 8742312
401 + 8741911 = 8742312
499 + 8741813 = 8742312

Showing the first eight; more decompositions exist.
