Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742122, here are decompositions:

19 + 8742103 = 8742122
139 + 8741983 = 8742122
199 + 8741923 = 8742122
211 + 8741911 = 8742122
283 + 8741839 = 8742122
373 + 8741749 = 8742122
379 + 8741743 = 8742122
439 + 8741683 = 8742122

Showing the first eight; more decompositions exist.
