Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018790, here are decompositions:

13 + 1018777 = 1018790
61 + 1018729 = 1018790
79 + 1018711 = 1018790
139 + 1018651 = 1018790
277 + 1018513 = 1018790
313 + 1018477 = 1018790
379 + 1018411 = 1018790
433 + 1018357 = 1018790

Showing the first eight; more decompositions exist.
