Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673820, here are decompositions:

3 + 8673817 = 8673820
59 + 8673761 = 8673820
137 + 8673683 = 8673820
227 + 8673593 = 8673820
251 + 8673569 = 8673820
401 + 8673419 = 8673820
431 + 8673389 = 8673820
443 + 8673377 = 8673820

Showing the first eight; more decompositions exist.
