Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642962, here are decompositions:

11 + 8642951 = 8642962
23 + 8642939 = 8642962
59 + 8642903 = 8642962
101 + 8642861 = 8642962
113 + 8642849 = 8642962
239 + 8642723 = 8642962
311 + 8642651 = 8642962
443 + 8642519 = 8642962

Showing the first eight; more decompositions exist.
