Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017782, here are decompositions:

61 + 1017721 = 1017782
79 + 1017703 = 1017782
109 + 1017673 = 1017782
223 + 1017559 = 1017782
229 + 1017553 = 1017782
421 + 1017361 = 1017782
463 + 1017319 = 1017782
643 + 1017139 = 1017782

Showing the first eight; more decompositions exist.
