Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715838, here are decompositions:

59 + 8715779 = 8715838
107 + 8715731 = 8715838
167 + 8715671 = 8715838
179 + 8715659 = 8715838
191 + 8715647 = 8715838
251 + 8715587 = 8715838
389 + 8715449 = 8715838
491 + 8715347 = 8715838

Showing the first eight; more decompositions exist.
