Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019986, here are decompositions:

59 + 1019927 = 1019986
83 + 1019903 = 1019986
113 + 1019873 = 1019986
137 + 1019849 = 1019986
167 + 1019819 = 1019986
239 + 1019747 = 1019986
257 + 1019729 = 1019986
263 + 1019723 = 1019986

Showing the first eight; more decompositions exist.
