Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101788, here are decompositions:

17 + 101771 = 101788
41 + 101747 = 101788
47 + 101741 = 101788
107 + 101681 = 101788
227 + 101561 = 101788
251 + 101537 = 101788
257 + 101531 = 101788
311 + 101477 = 101788

Showing the first eight; more decompositions exist.
