Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742392, here are decompositions:

13 + 8742379 = 8742392
79 + 8742313 = 8742392
199 + 8742193 = 8742392
223 + 8742169 = 8742392
271 + 8742121 = 8742392
409 + 8741983 = 8742392
613 + 8741779 = 8742392
643 + 8741749 = 8742392

Showing the first eight; more decompositions exist.
