Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623982, here are decompositions:

13 + 8623969 = 8623982
19 + 8623963 = 8623982
43 + 8623939 = 8623982
79 + 8623903 = 8623982
139 + 8623843 = 8623982
151 + 8623831 = 8623982
181 + 8623801 = 8623982
331 + 8623651 = 8623982

Showing the first eight; more decompositions exist.
