Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622730, here are decompositions:

23 + 8622707 = 8622730
47 + 8622683 = 8622730
167 + 8622563 = 8622730
239 + 8622491 = 8622730
257 + 8622473 = 8622730
269 + 8622461 = 8622730
317 + 8622413 = 8622730
443 + 8622287 = 8622730

Showing the first eight; more decompositions exist.
