Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749556, here are decompositions:

7 + 8749549 = 8749556
139 + 8749417 = 8749556
199 + 8749357 = 8749556
313 + 8749243 = 8749556
337 + 8749219 = 8749556
349 + 8749207 = 8749556
577 + 8748979 = 8749556
709 + 8748847 = 8749556

Showing the first eight; more decompositions exist.
