Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622784, here are decompositions:

3 + 8622781 = 8622784
17 + 8622767 = 8622784
101 + 8622683 = 8622784
173 + 8622611 = 8622784
263 + 8622521 = 8622784
293 + 8622491 = 8622784
311 + 8622473 = 8622784
431 + 8622353 = 8622784

Showing the first eight; more decompositions exist.
