Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744880, here are decompositions:

19 + 8744861 = 8744880
37 + 8744843 = 8744880
43 + 8744837 = 8744880
47 + 8744833 = 8744880
61 + 8744819 = 8744880
163 + 8744717 = 8744880
173 + 8744707 = 8744880
197 + 8744683 = 8744880

Showing the first eight; more decompositions exist.
