Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625542, here are decompositions:

193 + 8625349 = 8625542
199 + 8625343 = 8625542
229 + 8625313 = 8625542
241 + 8625301 = 8625542
313 + 8625229 = 8625542
421 + 8625121 = 8625542
613 + 8624929 = 8625542
661 + 8624881 = 8625542

Showing the first eight; more decompositions exist.
