Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601578, here are decompositions:

67 + 8601511 = 8601578
79 + 8601499 = 8601578
157 + 8601421 = 8601578
409 + 8601169 = 8601578
421 + 8601157 = 8601578
457 + 8601121 = 8601578
541 + 8601037 = 8601578
607 + 8600971 = 8601578

Showing the first eight; more decompositions exist.
