Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140858, here are decompositions:

19 + 140839 = 140858
31 + 140827 = 140858
61 + 140797 = 140858
79 + 140779 = 140858
97 + 140761 = 140858
127 + 140731 = 140858
181 + 140677 = 140858
199 + 140659 = 140858

Showing the first eight; more decompositions exist.
