Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744228, here are decompositions:

37 + 8744191 = 8744228
79 + 8744149 = 8744228
127 + 8744101 = 8744228
349 + 8743879 = 8744228
421 + 8743807 = 8744228
457 + 8743771 = 8744228
547 + 8743681 = 8744228
607 + 8743621 = 8744228

Showing the first eight; more decompositions exist.
