Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660228, here are decompositions:

7 + 8660221 = 8660228
67 + 8660161 = 8660228
151 + 8660077 = 8660228
229 + 8659999 = 8660228
271 + 8659957 = 8660228
307 + 8659921 = 8660228
487 + 8659741 = 8660228
601 + 8659627 = 8660228

Showing the first eight; more decompositions exist.
