Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670920, here are decompositions:

109 + 8670811 = 8670920
211 + 8670709 = 8670920
241 + 8670679 = 8670920
283 + 8670637 = 8670920
331 + 8670589 = 8670920
337 + 8670583 = 8670920
367 + 8670553 = 8670920
397 + 8670523 = 8670920

Showing the first eight; more decompositions exist.
