Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625622, here are decompositions:

23 + 8625599 = 8625622
101 + 8625521 = 8625622
113 + 8625509 = 8625622
191 + 8625431 = 8625622
263 + 8625359 = 8625622
311 + 8625311 = 8625622
359 + 8625263 = 8625622
389 + 8625233 = 8625622

Showing the first eight; more decompositions exist.
