Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625684, here are decompositions:

43 + 8625641 = 8625684
47 + 8625637 = 8625684
97 + 8625587 = 8625684
131 + 8625553 = 8625684
157 + 8625527 = 8625684
163 + 8625521 = 8625684
167 + 8625517 = 8625684
191 + 8625493 = 8625684

Showing the first eight; more decompositions exist.
