Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742166, here are decompositions:

5 + 8742161 = 8742166
89 + 8742077 = 8742166
107 + 8742059 = 8742166
179 + 8741987 = 8742166
233 + 8741933 = 8742166
353 + 8741813 = 8742166
467 + 8741699 = 8742166
479 + 8741687 = 8742166

Showing the first eight; more decompositions exist.
