Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662742, here are decompositions:

13 + 8662729 = 8662742
163 + 8662579 = 8662742
211 + 8662531 = 8662742
271 + 8662471 = 8662742
331 + 8662411 = 8662742
463 + 8662279 = 8662742
499 + 8662243 = 8662742
523 + 8662219 = 8662742

Showing the first eight; more decompositions exist.
