Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710820, here are decompositions:

73 + 8710747 = 8710820
103 + 8710717 = 8710820
127 + 8710693 = 8710820
193 + 8710627 = 8710820
199 + 8710621 = 8710820
211 + 8710609 = 8710820
337 + 8710483 = 8710820
379 + 8710441 = 8710820

Showing the first eight; more decompositions exist.
