Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82700, here are decompositions:

43 + 82657 = 82700
67 + 82633 = 82700
109 + 82591 = 82700
139 + 82561 = 82700
151 + 82549 = 82700
193 + 82507 = 82700
229 + 82471 = 82700
307 + 82393 = 82700

Showing the first eight; more decompositions exist.
