Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002218, here are decompositions:

67 + 1002151 = 1002218
97 + 1002121 = 1002218
109 + 1002109 = 1002218
127 + 1002091 = 1002218
157 + 1002061 = 1002218
229 + 1001989 = 1002218
241 + 1001977 = 1002218
271 + 1001947 = 1002218

Showing the first eight; more decompositions exist.
