Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713420, here are decompositions:

17 + 8713403 = 8713420
47 + 8713373 = 8713420
71 + 8713349 = 8713420
101 + 8713319 = 8713420
113 + 8713307 = 8713420
227 + 8713193 = 8713420
239 + 8713181 = 8713420
263 + 8713157 = 8713420

Showing the first eight; more decompositions exist.
