Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625746, here are decompositions:

13 + 8625733 = 8625746
37 + 8625709 = 8625746
97 + 8625649 = 8625746
109 + 8625637 = 8625746
193 + 8625553 = 8625746
229 + 8625517 = 8625746
397 + 8625349 = 8625746
433 + 8625313 = 8625746

Showing the first eight; more decompositions exist.
