Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713820, here are decompositions:

7 + 8713813 = 8713820
13 + 8713807 = 8713820
127 + 8713693 = 8713820
229 + 8713591 = 8713820
307 + 8713513 = 8713820
373 + 8713447 = 8713820
421 + 8713399 = 8713820
457 + 8713363 = 8713820

Showing the first eight; more decompositions exist.
