Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013866, here are decompositions:

23 + 1013843 = 1013866
47 + 1013819 = 1013866
53 + 1013813 = 1013866
137 + 1013729 = 1013866
149 + 1013717 = 1013866
167 + 1013699 = 1013866
179 + 1013687 = 1013866
239 + 1013627 = 1013866

Showing the first eight; more decompositions exist.
