Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673778, here are decompositions:

17 + 8673761 = 8673778
101 + 8673677 = 8673778
167 + 8673611 = 8673778
359 + 8673419 = 8673778
389 + 8673389 = 8673778
401 + 8673377 = 8673778
419 + 8673359 = 8673778
431 + 8673347 = 8673778

Showing the first eight; more decompositions exist.
