Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101822, here are decompositions:

73 + 101749 = 101822
103 + 101719 = 101822
181 + 101641 = 101822
211 + 101611 = 101822
223 + 101599 = 101822
241 + 101581 = 101822
373 + 101449 = 101822
439 + 101383 = 101822

Showing the first eight; more decompositions exist.
