Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678458, here are decompositions:

11 + 8678447 = 8678458
59 + 8678399 = 8678458
311 + 8678147 = 8678458
317 + 8678141 = 8678458
389 + 8678069 = 8678458
401 + 8678057 = 8678458
419 + 8678039 = 8678458
431 + 8678027 = 8678458

Showing the first eight; more decompositions exist.
