Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749328, here are decompositions:

19 + 8749309 = 8749328
109 + 8749219 = 8749328
241 + 8749087 = 8749328
337 + 8748991 = 8749328
349 + 8748979 = 8749328
439 + 8748889 = 8749328
487 + 8748841 = 8749328
541 + 8748787 = 8749328

Showing the first eight; more decompositions exist.
