Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742214, here are decompositions:

17 + 8742197 = 8742214
53 + 8742161 = 8742214
137 + 8742077 = 8742214
227 + 8741987 = 8742214
263 + 8741951 = 8742214
281 + 8741933 = 8742214
347 + 8741867 = 8742214
353 + 8741861 = 8742214

Showing the first eight; more decompositions exist.
