Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742066, here are decompositions:

7 + 8742059 = 8742066
29 + 8742037 = 8742066
79 + 8741987 = 8742066
83 + 8741983 = 8742066
89 + 8741977 = 8742066
199 + 8741867 = 8742066
227 + 8741839 = 8742066
269 + 8741797 = 8742066

Showing the first eight; more decompositions exist.
