Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983780, here are decompositions:

3 + 983777 = 983780
43 + 983737 = 983780
79 + 983701 = 983780
163 + 983617 = 983780
199 + 983581 = 983780
223 + 983557 = 983780
331 + 983449 = 983780
337 + 983443 = 983780

Showing the first eight; more decompositions exist.
