Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101894, here are decompositions:

3 + 101891 = 101894
31 + 101863 = 101894
61 + 101833 = 101894
97 + 101797 = 101894
157 + 101737 = 101894
193 + 101701 = 101894
241 + 101653 = 101894
283 + 101611 = 101894

Showing the first eight; more decompositions exist.
