Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020218, here are decompositions:

61 + 1020157 = 1020218
109 + 1020109 = 1020218
139 + 1020079 = 1020218
181 + 1020037 = 1020218
211 + 1020007 = 1020218
379 + 1019839 = 1020218
487 + 1019731 = 1020218
571 + 1019647 = 1020218

Showing the first eight; more decompositions exist.
