Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711780, here are decompositions:

3 + 8711777 = 8711780
13 + 8711767 = 8711780
31 + 8711749 = 8711780
37 + 8711743 = 8711780
43 + 8711737 = 8711780
61 + 8711719 = 8711780
73 + 8711707 = 8711780
97 + 8711683 = 8711780

Showing the first eight; more decompositions exist.
