Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715398, here are decompositions:

37 + 8715361 = 8715398
61 + 8715337 = 8715398
379 + 8715019 = 8715398
409 + 8714989 = 8715398
457 + 8714941 = 8715398
541 + 8714857 = 8715398
577 + 8714821 = 8715398
619 + 8714779 = 8715398

Showing the first eight; more decompositions exist.
