Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706078, here are decompositions:

5 + 8706073 = 8706078
19 + 8706059 = 8706078
67 + 8706011 = 8706078
71 + 8706007 = 8706078
79 + 8705999 = 8706078
109 + 8705969 = 8706078
137 + 8705941 = 8706078
167 + 8705911 = 8706078

Showing the first eight; more decompositions exist.
