Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101912, here are decompositions:

43 + 101869 = 101912
73 + 101839 = 101912
79 + 101833 = 101912
163 + 101749 = 101912
193 + 101719 = 101912
211 + 101701 = 101912
271 + 101641 = 101912
313 + 101599 = 101912

Showing the first eight; more decompositions exist.
