Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601218, here are decompositions:

61 + 8601157 = 8601218
97 + 8601121 = 8601218
181 + 8601037 = 8601218
271 + 8600947 = 8601218
277 + 8600941 = 8601218
337 + 8600881 = 8601218
499 + 8600719 = 8601218
541 + 8600677 = 8601218

Showing the first eight; more decompositions exist.
