Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676820, here are decompositions:

41 + 8676779 = 8676820
101 + 8676719 = 8676820
179 + 8676641 = 8676820
233 + 8676587 = 8676820
293 + 8676527 = 8676820
353 + 8676467 = 8676820
389 + 8676431 = 8676820
419 + 8676401 = 8676820

Showing the first eight; more decompositions exist.
