Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010780, here are decompositions:

13 + 1010767 = 1010780
31 + 1010749 = 1010780
61 + 1010719 = 1010780
97 + 1010683 = 1010780
109 + 1010671 = 1010780
157 + 1010623 = 1010780
163 + 1010617 = 1010780
271 + 1010509 = 1010780

Showing the first eight; more decompositions exist.
