Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713840, here are decompositions:

17 + 8713823 = 8713840
29 + 8713811 = 8713840
59 + 8713781 = 8713840
131 + 8713709 = 8713840
197 + 8713643 = 8713840
257 + 8713583 = 8713840
263 + 8713577 = 8713840
293 + 8713547 = 8713840

Showing the first eight; more decompositions exist.
