Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722706, here are decompositions:

103 + 8722603 = 8722706
229 + 8722477 = 8722706
277 + 8722429 = 8722706
283 + 8722423 = 8722706
313 + 8722393 = 8722706
367 + 8722339 = 8722706
373 + 8722333 = 8722706
409 + 8722297 = 8722706

Showing the first eight; more decompositions exist.
