Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101884, here are decompositions:

5 + 101879 = 101884
11 + 101873 = 101884
47 + 101837 = 101884
113 + 101771 = 101884
137 + 101747 = 101884
191 + 101693 = 101884
257 + 101627 = 101884
281 + 101603 = 101884

Showing the first eight; more decompositions exist.
