Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722712, here are decompositions:

109 + 8722603 = 8722712
241 + 8722471 = 8722712
283 + 8722429 = 8722712
373 + 8722339 = 8722712
379 + 8722333 = 8722712
409 + 8722303 = 8722712
421 + 8722291 = 8722712
541 + 8722171 = 8722712

Showing the first eight; more decompositions exist.
