Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726148, here are decompositions:

5 + 8726143 = 8726148
7 + 8726141 = 8726148
47 + 8726101 = 8726148
61 + 8726087 = 8726148
97 + 8726051 = 8726148
127 + 8726021 = 8726148
131 + 8726017 = 8726148
149 + 8725999 = 8726148

Showing the first eight; more decompositions exist.
