Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101826, here are decompositions:

19 + 101807 = 101826
29 + 101797 = 101826
37 + 101789 = 101826
79 + 101747 = 101826
89 + 101737 = 101826
103 + 101723 = 101826
107 + 101719 = 101826
163 + 101663 = 101826

Showing the first eight; more decompositions exist.
