Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013780, here are decompositions:

7 + 1013773 = 1013780
13 + 1013767 = 1013780
67 + 1013713 = 1013780
109 + 1013671 = 1013780
139 + 1013641 = 1013780
151 + 1013629 = 1013780
199 + 1013581 = 1013780
211 + 1013569 = 1013780

Showing the first eight; more decompositions exist.
