Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732178, here are decompositions:

19 + 8732159 = 8732178
41 + 8732137 = 8732178
61 + 8732117 = 8732178
97 + 8732081 = 8732178
107 + 8732071 = 8732178
127 + 8732051 = 8732178
131 + 8732047 = 8732178
149 + 8732029 = 8732178

Showing the first eight; more decompositions exist.
