Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622772, here are decompositions:

5 + 8622767 = 8622772
89 + 8622683 = 8622772
251 + 8622521 = 8622772
281 + 8622491 = 8622772
311 + 8622461 = 8622772
359 + 8622413 = 8622772
419 + 8622353 = 8622772
449 + 8622323 = 8622772

Showing the first eight; more decompositions exist.
