Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011866, here are decompositions:

67 + 1011799 = 1011866
103 + 1011763 = 1011866
199 + 1011667 = 1011866
277 + 1011589 = 1011866
283 + 1011583 = 1011866
307 + 1011559 = 1011866
313 + 1011553 = 1011866
523 + 1011343 = 1011866

Showing the first eight; more decompositions exist.
