Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673890, here are decompositions:

13 + 8673877 = 8673890
73 + 8673817 = 8673890
109 + 8673781 = 8673890
163 + 8673727 = 8673890
373 + 8673517 = 8673890
457 + 8673433 = 8673890
619 + 8673271 = 8673890
691 + 8673199 = 8673890

Showing the first eight; more decompositions exist.
