Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722286, here are decompositions:

3 + 8722283 = 8722286
163 + 8722123 = 8722286
193 + 8722093 = 8722286
277 + 8722009 = 8722286
373 + 8721913 = 8722286
379 + 8721907 = 8722286
409 + 8721877 = 8722286
523 + 8721763 = 8722286

Showing the first eight; more decompositions exist.
