Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667982, here are decompositions:

3 + 8667979 = 8667982
53 + 8667929 = 8667982
83 + 8667899 = 8667982
173 + 8667809 = 8667982
293 + 8667689 = 8667982
419 + 8667563 = 8667982
443 + 8667539 = 8667982
461 + 8667521 = 8667982

Showing the first eight; more decompositions exist.
