Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102722, here are decompositions:

43 + 102679 = 102722
79 + 102643 = 102722
163 + 102559 = 102722
199 + 102523 = 102722
223 + 102499 = 102722
241 + 102481 = 102722
271 + 102451 = 102722
313 + 102409 = 102722

Showing the first eight; more decompositions exist.
