Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670806, here are decompositions:

97 + 8670709 = 8670806
103 + 8670703 = 8670806
127 + 8670679 = 8670806
139 + 8670667 = 8670806
223 + 8670583 = 8670806
283 + 8670523 = 8670806
307 + 8670499 = 8670806
373 + 8670433 = 8670806

Showing the first eight; more decompositions exist.
