Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71486, here are decompositions:

3 + 71483 = 71486
7 + 71479 = 71486
13 + 71473 = 71486
43 + 71443 = 71486
67 + 71419 = 71486
73 + 71413 = 71486
97 + 71389 = 71486
127 + 71359 = 71486

Showing the first eight; more decompositions exist.
