Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71814, here are decompositions:

5 + 71809 = 71814
7 + 71807 = 71814
37 + 71777 = 71814
53 + 71761 = 71814
73 + 71741 = 71814
101 + 71713 = 71814
103 + 71711 = 71814
107 + 71707 = 71814

Showing the first eight; more decompositions exist.
