Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101680, here are decompositions:

17 + 101663 = 101680
53 + 101627 = 101680
107 + 101573 = 101680
149 + 101531 = 101680
167 + 101513 = 101680
179 + 101501 = 101680
191 + 101489 = 101680
197 + 101483 = 101680

Showing the first eight; more decompositions exist.
