Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728962, here are decompositions:

19 + 8728943 = 8728962
41 + 8728921 = 8728962
59 + 8728903 = 8728962
61 + 8728901 = 8728962
79 + 8728883 = 8728962
113 + 8728849 = 8728962
139 + 8728823 = 8728962
241 + 8728721 = 8728962

Showing the first eight; more decompositions exist.
