Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744872, here are decompositions:

11 + 8744861 = 8744872
29 + 8744843 = 8744872
41 + 8744831 = 8744872
53 + 8744819 = 8744872
359 + 8744513 = 8744872
449 + 8744423 = 8744872
683 + 8744189 = 8744872
743 + 8744129 = 8744872

Showing the first eight; more decompositions exist.
