Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649862, here are decompositions:

5 + 8649857 = 8649862
59 + 8649803 = 8649862
71 + 8649791 = 8649862
101 + 8649761 = 8649862
173 + 8649689 = 8649862
191 + 8649671 = 8649862
233 + 8649629 = 8649862
239 + 8649623 = 8649862

Showing the first eight; more decompositions exist.
