Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013878, here are decompositions:

59 + 1013819 = 1013878
137 + 1013741 = 1013878
149 + 1013729 = 1013878
167 + 1013711 = 1013878
179 + 1013699 = 1013878
191 + 1013687 = 1013878
197 + 1013681 = 1013878
251 + 1013627 = 1013878

Showing the first eight; more decompositions exist.
