Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71426, here are decompositions:

7 + 71419 = 71426
13 + 71413 = 71426
37 + 71389 = 71426
67 + 71359 = 71426
73 + 71353 = 71426
79 + 71347 = 71426
97 + 71329 = 71426
109 + 71317 = 71426

Showing the first eight; more decompositions exist.
