Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101858, here are decompositions:

19 + 101839 = 101858
61 + 101797 = 101858
109 + 101749 = 101858
139 + 101719 = 101858
157 + 101701 = 101858
277 + 101581 = 101858
331 + 101527 = 101858
409 + 101449 = 101858

Showing the first eight; more decompositions exist.
