Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013786, here are decompositions:

13 + 1013773 = 1013786
19 + 1013767 = 1013786
73 + 1013713 = 1013786
157 + 1013629 = 1013786
223 + 1013563 = 1013786
283 + 1013503 = 1013786
409 + 1013377 = 1013786
457 + 1013329 = 1013786

Showing the first eight; more decompositions exist.
