Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673686, here are decompositions:

3 + 8673683 = 8673686
139 + 8673547 = 8673686
223 + 8673463 = 8673686
313 + 8673373 = 8673686
487 + 8673199 = 8673686
499 + 8673187 = 8673686
577 + 8673109 = 8673686
613 + 8673073 = 8673686

Showing the first eight; more decompositions exist.
