Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742446, here are decompositions:

67 + 8742379 = 8742446
79 + 8742367 = 8742446
277 + 8742169 = 8742446
313 + 8742133 = 8742446
379 + 8742067 = 8742446
409 + 8742037 = 8742446
457 + 8741989 = 8742446
463 + 8741983 = 8742446

Showing the first eight; more decompositions exist.
