Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660198, here are decompositions:

37 + 8660161 = 8660198
199 + 8659999 = 8660198
241 + 8659957 = 8660198
271 + 8659927 = 8660198
277 + 8659921 = 8660198
331 + 8659867 = 8660198
457 + 8659741 = 8660198
487 + 8659711 = 8660198

Showing the first eight; more decompositions exist.
