Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013842, here are decompositions:

3 + 1013839 = 1013842
23 + 1013819 = 1013842
29 + 1013813 = 1013842
101 + 1013741 = 1013842
113 + 1013729 = 1013842
131 + 1013711 = 1013842
233 + 1013609 = 1013842
239 + 1013603 = 1013842

Showing the first eight; more decompositions exist.
