Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637980, here are decompositions:

7 + 8637973 = 8637980
37 + 8637943 = 8637980
151 + 8637829 = 8637980
193 + 8637787 = 8637980
283 + 8637697 = 8637980
313 + 8637667 = 8637980
457 + 8637523 = 8637980
487 + 8637493 = 8637980

Showing the first eight; more decompositions exist.
