Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173810, here are decompositions:

3 + 173807 = 173810
31 + 173779 = 173810
37 + 173773 = 173810
67 + 173743 = 173810
97 + 173713 = 173810
103 + 173707 = 173810
127 + 173683 = 173810
139 + 173671 = 173810

Showing the first eight; more decompositions exist.
