Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013986, here are decompositions:

53 + 1013933 = 1013986
107 + 1013879 = 1013986
167 + 1013819 = 1013986
173 + 1013813 = 1013986
257 + 1013729 = 1013986
269 + 1013717 = 1013986
359 + 1013627 = 1013986
383 + 1013603 = 1013986

Showing the first eight; more decompositions exist.
