Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027780, here are decompositions:

3 + 1027777 = 1027780
23 + 1027757 = 1027780
29 + 1027751 = 1027780
41 + 1027739 = 1027780
53 + 1027727 = 1027780
101 + 1027679 = 1027780
137 + 1027643 = 1027780
167 + 1027613 = 1027780

Showing the first eight; more decompositions exist.
