Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738718, here are decompositions:

5 + 8738713 = 8738718
7 + 8738711 = 8738718
11 + 8738707 = 8738718
47 + 8738671 = 8738718
59 + 8738659 = 8738718
127 + 8738591 = 8738718
137 + 8738581 = 8738718
139 + 8738579 = 8738718

Showing the first eight; more decompositions exist.
