Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101850, here are decompositions:

11 + 101839 = 101850
13 + 101837 = 101850
17 + 101833 = 101850
43 + 101807 = 101850
53 + 101797 = 101850
61 + 101789 = 101850
79 + 101771 = 101850
101 + 101749 = 101850

Showing the first eight; more decompositions exist.
