Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71420, here are decompositions:

7 + 71413 = 71420
31 + 71389 = 71420
61 + 71359 = 71420
67 + 71353 = 71420
73 + 71347 = 71420
79 + 71341 = 71420
103 + 71317 = 71420
127 + 71293 = 71420

Showing the first eight; more decompositions exist.
