Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737820, here are decompositions:

19 + 8737801 = 8737820
31 + 8737789 = 8737820
37 + 8737783 = 8737820
79 + 8737741 = 8737820
103 + 8737717 = 8737820
127 + 8737693 = 8737820
151 + 8737669 = 8737820
163 + 8737657 = 8737820

Showing the first eight; more decompositions exist.
