Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738880, here are decompositions:

37 + 8738843 = 8738880
41 + 8738839 = 8738880
43 + 8738837 = 8738880
67 + 8738813 = 8738880
71 + 8738809 = 8738880
79 + 8738801 = 8738880
97 + 8738783 = 8738880
113 + 8738767 = 8738880

Showing the first eight; more decompositions exist.
