Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23720, here are decompositions:

31 + 23689 = 23720
43 + 23677 = 23720
97 + 23623 = 23720
127 + 23593 = 23720
139 + 23581 = 23720
157 + 23563 = 23720
163 + 23557 = 23720
181 + 23539 = 23720

Showing the first eight; more decompositions exist.
