Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749232, here are decompositions:

3 + 8749229 = 8749232
13 + 8749219 = 8749232
241 + 8748991 = 8749232
379 + 8748853 = 8749232
421 + 8748811 = 8749232
523 + 8748709 = 8749232
631 + 8748601 = 8749232
643 + 8748589 = 8749232

Showing the first eight; more decompositions exist.
