Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749820, here are decompositions:

3 + 8749817 = 8749820
7 + 8749813 = 8749820
31 + 8749789 = 8749820
67 + 8749753 = 8749820
151 + 8749669 = 8749820
193 + 8749627 = 8749820
241 + 8749579 = 8749820
271 + 8749549 = 8749820

Showing the first eight; more decompositions exist.
