Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678378, here are decompositions:

19 + 8678359 = 8678378
67 + 8678311 = 8678378
199 + 8678179 = 8678378
229 + 8678149 = 8678378
349 + 8678029 = 8678378
367 + 8678011 = 8678378
487 + 8677891 = 8678378
607 + 8677771 = 8678378

Showing the first eight; more decompositions exist.
