Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758820, here are decompositions:

19 + 8758801 = 8758820
43 + 8758777 = 8758820
73 + 8758747 = 8758820
151 + 8758669 = 8758820
223 + 8758597 = 8758820
271 + 8758549 = 8758820
283 + 8758537 = 8758820
307 + 8758513 = 8758820

Showing the first eight; more decompositions exist.
