Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726422, here are decompositions:

41 + 8726381 = 8726422
59 + 8726363 = 8726422
71 + 8726351 = 8726422
149 + 8726273 = 8726422
179 + 8726243 = 8726422
281 + 8726141 = 8726422
359 + 8726063 = 8726422
401 + 8726021 = 8726422

Showing the first eight; more decompositions exist.
