Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625558, here are decompositions:

5 + 8625553 = 8625558
17 + 8625541 = 8625558
31 + 8625527 = 8625558
37 + 8625521 = 8625558
41 + 8625517 = 8625558
79 + 8625479 = 8625558
107 + 8625451 = 8625558
127 + 8625431 = 8625558

Showing the first eight; more decompositions exist.
