Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140810, here are decompositions:

13 + 140797 = 140810
31 + 140779 = 140810
37 + 140773 = 140810
79 + 140731 = 140810
127 + 140683 = 140810
151 + 140659 = 140810
181 + 140629 = 140810
193 + 140617 = 140810

Showing the first eight; more decompositions exist.
