Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38700, here are decompositions:

7 + 38693 = 38700
23 + 38677 = 38700
29 + 38671 = 38700
31 + 38669 = 38700
47 + 38653 = 38700
61 + 38639 = 38700
71 + 38629 = 38700
89 + 38611 = 38700

Showing the first eight; more decompositions exist.
