Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712980, here are decompositions:

7 + 8712973 = 8712980
61 + 8712919 = 8712980
223 + 8712757 = 8712980
229 + 8712751 = 8712980
271 + 8712709 = 8712980
379 + 8712601 = 8712980
433 + 8712547 = 8712980
457 + 8712523 = 8712980

Showing the first eight; more decompositions exist.
