Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743178, here are decompositions:

79 + 8743099 = 8743178
151 + 8743027 = 8743178
181 + 8742997 = 8743178
331 + 8742847 = 8743178
439 + 8742739 = 8743178
541 + 8742637 = 8743178
601 + 8742577 = 8743178
607 + 8742571 = 8743178

Showing the first eight; more decompositions exist.
