Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738788, here are decompositions:

5 + 8738783 = 8738788
29 + 8738759 = 8738788
59 + 8738729 = 8738788
197 + 8738591 = 8738788
281 + 8738507 = 8738788
389 + 8738399 = 8738788
449 + 8738339 = 8738788
557 + 8738231 = 8738788

Showing the first eight; more decompositions exist.
