Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742208, here are decompositions:

11 + 8742197 = 8742208
47 + 8742161 = 8742208
131 + 8742077 = 8742208
149 + 8742059 = 8742208
197 + 8742011 = 8742208
257 + 8741951 = 8742208
347 + 8741861 = 8742208
467 + 8741741 = 8742208

Showing the first eight; more decompositions exist.
