Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71826, here are decompositions:

5 + 71821 = 71826
17 + 71809 = 71826
19 + 71807 = 71826
37 + 71789 = 71826
107 + 71719 = 71826
113 + 71713 = 71826
127 + 71699 = 71826
163 + 71663 = 71826

Showing the first eight; more decompositions exist.
