Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101854, here are decompositions:

17 + 101837 = 101854
47 + 101807 = 101854
83 + 101771 = 101854
107 + 101747 = 101854
113 + 101741 = 101854
131 + 101723 = 101854
173 + 101681 = 101854
191 + 101663 = 101854

Showing the first eight; more decompositions exist.
