Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744528, here are decompositions:

31 + 8744497 = 8744528
61 + 8744467 = 8744528
109 + 8744419 = 8744528
211 + 8744317 = 8744528
337 + 8744191 = 8744528
379 + 8744149 = 8744528
487 + 8744041 = 8744528
547 + 8743981 = 8744528

Showing the first eight; more decompositions exist.
