Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38718, here are decompositions:

5 + 38713 = 38718
7 + 38711 = 38718
11 + 38707 = 38718
19 + 38699 = 38718
41 + 38677 = 38718
47 + 38671 = 38718
67 + 38651 = 38718
79 + 38639 = 38718

Showing the first eight; more decompositions exist.
