Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726474, here are decompositions:

7 + 8726467 = 8726474
13 + 8726461 = 8726474
73 + 8726401 = 8726474
151 + 8726323 = 8726474
271 + 8726203 = 8726474
277 + 8726197 = 8726474
331 + 8726143 = 8726474
373 + 8726101 = 8726474

Showing the first eight; more decompositions exist.
