Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013818, here are decompositions:

5 + 1013813 = 1013818
89 + 1013729 = 1013818
101 + 1013717 = 1013818
107 + 1013711 = 1013818
131 + 1013687 = 1013818
137 + 1013681 = 1013818
191 + 1013627 = 1013818
317 + 1013501 = 1013818

Showing the first eight; more decompositions exist.
