Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 976820, here are decompositions:

3 + 976817 = 976820
43 + 976777 = 976820
151 + 976669 = 976820
181 + 976639 = 976820
199 + 976621 = 976820
283 + 976537 = 976820
307 + 976513 = 976820
331 + 976489 = 976820

Showing the first eight; more decompositions exist.
