Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711390, here are decompositions:

3 + 8711387 = 8711390
7 + 8711383 = 8711390
13 + 8711377 = 8711390
31 + 8711359 = 8711390
43 + 8711347 = 8711390
211 + 8711179 = 8711390
229 + 8711161 = 8711390
307 + 8711083 = 8711390

Showing the first eight; more decompositions exist.
