Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101892, here are decompositions:

13 + 101879 = 101892
19 + 101873 = 101892
23 + 101869 = 101892
29 + 101863 = 101892
53 + 101839 = 101892
59 + 101833 = 101892
103 + 101789 = 101892
151 + 101741 = 101892

Showing the first eight; more decompositions exist.
