Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678542, here are decompositions:

23 + 8678519 = 8678542
149 + 8678393 = 8678542
179 + 8678363 = 8678542
401 + 8678141 = 8678542
449 + 8678093 = 8678542
461 + 8678081 = 8678542
479 + 8678063 = 8678542
491 + 8678051 = 8678542

Showing the first eight; more decompositions exist.
