Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673978, here are decompositions:

37 + 8673941 = 8673978
67 + 8673911 = 8673978
101 + 8673877 = 8673978
139 + 8673839 = 8673978
197 + 8673781 = 8673978
251 + 8673727 = 8673978
367 + 8673611 = 8673978
409 + 8673569 = 8673978

Showing the first eight; more decompositions exist.
