Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71810, here are decompositions:

3 + 71807 = 71810
97 + 71713 = 71810
103 + 71707 = 71810
139 + 71671 = 71810
163 + 71647 = 71810
241 + 71569 = 71810
283 + 71527 = 71810
307 + 71503 = 71810

Showing the first eight; more decompositions exist.
