Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101618, here are decompositions:

7 + 101611 = 101618
19 + 101599 = 101618
37 + 101581 = 101618
151 + 101467 = 101618
199 + 101419 = 101618
241 + 101377 = 101618
271 + 101347 = 101618
277 + 101341 = 101618

Showing the first eight; more decompositions exist.
