Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713978, here are decompositions:

17 + 8713961 = 8713978
47 + 8713931 = 8713978
59 + 8713919 = 8713978
167 + 8713811 = 8713978
197 + 8713781 = 8713978
257 + 8713721 = 8713978
269 + 8713709 = 8713978
347 + 8713631 = 8713978

Showing the first eight; more decompositions exist.
