Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670980, here are decompositions:

37 + 8670943 = 8670980
61 + 8670919 = 8670980
229 + 8670751 = 8670980
271 + 8670709 = 8670980
277 + 8670703 = 8670980
313 + 8670667 = 8670980
397 + 8670583 = 8670980
421 + 8670559 = 8670980

Showing the first eight; more decompositions exist.
