Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744438, here are decompositions:

19 + 8744419 = 8744438
211 + 8744227 = 8744438
337 + 8744101 = 8744438
397 + 8744041 = 8744438
457 + 8743981 = 8744438
601 + 8743837 = 8744438
631 + 8743807 = 8744438
691 + 8743747 = 8744438

Showing the first eight; more decompositions exist.
