Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718426, here are decompositions:

7 + 8718419 = 8718426
19 + 8718407 = 8718426
83 + 8718343 = 8718426
113 + 8718313 = 8718426
149 + 8718277 = 8718426
179 + 8718247 = 8718426
229 + 8718197 = 8718426
263 + 8718163 = 8718426

Showing the first eight; more decompositions exist.
