Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742328, here are decompositions:

11 + 8742317 = 8742328
131 + 8742197 = 8742328
167 + 8742161 = 8742328
251 + 8742077 = 8742328
269 + 8742059 = 8742328
317 + 8742011 = 8742328
461 + 8741867 = 8742328
467 + 8741861 = 8742328

Showing the first eight; more decompositions exist.
