Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656378, here are decompositions:

11 + 8656367 = 8656378
281 + 8656097 = 8656378
347 + 8656031 = 8656378
359 + 8656019 = 8656378
461 + 8655917 = 8656378
509 + 8655869 = 8656378
569 + 8655809 = 8656378
617 + 8655761 = 8656378

Showing the first eight; more decompositions exist.
