Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47700, here are decompositions:

19 + 47681 = 47700
41 + 47659 = 47700
43 + 47657 = 47700
47 + 47653 = 47700
61 + 47639 = 47700
71 + 47629 = 47700
101 + 47599 = 47700
109 + 47591 = 47700

Showing the first eight; more decompositions exist.
