Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742432, here are decompositions:

11 + 8742421 = 8742432
31 + 8742401 = 8742432
53 + 8742379 = 8742432
73 + 8742359 = 8742432
79 + 8742353 = 8742432
173 + 8742259 = 8742432
239 + 8742193 = 8742432
263 + 8742169 = 8742432

Showing the first eight; more decompositions exist.
