Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712638, here are decompositions:

37 + 8712601 = 8712638
61 + 8712577 = 8712638
241 + 8712397 = 8712638
271 + 8712367 = 8712638
331 + 8712307 = 8712638
379 + 8712259 = 8712638
409 + 8712229 = 8712638
457 + 8712181 = 8712638

Showing the first eight; more decompositions exist.
