Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71480, here are decompositions:

7 + 71473 = 71480
37 + 71443 = 71480
43 + 71437 = 71480
61 + 71419 = 71480
67 + 71413 = 71480
127 + 71353 = 71480
139 + 71341 = 71480
151 + 71329 = 71480

Showing the first eight; more decompositions exist.
