Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726242, here are decompositions:

3 + 8726239 = 8726242
101 + 8726141 = 8726242
149 + 8726093 = 8726242
179 + 8726063 = 8726242
191 + 8726051 = 8726242
251 + 8725991 = 8726242
263 + 8725979 = 8726242
281 + 8725961 = 8726242

Showing the first eight; more decompositions exist.
