Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101916, here are decompositions:

37 + 101879 = 101916
43 + 101873 = 101916
47 + 101869 = 101916
53 + 101863 = 101916
79 + 101837 = 101916
83 + 101833 = 101916
109 + 101807 = 101916
127 + 101789 = 101916

Showing the first eight; more decompositions exist.
