Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101874, here are decompositions:

5 + 101869 = 101874
11 + 101863 = 101874
37 + 101837 = 101874
41 + 101833 = 101874
67 + 101807 = 101874
103 + 101771 = 101874
127 + 101747 = 101874
137 + 101737 = 101874

Showing the first eight; more decompositions exist.
