Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71472, here are decompositions:

19 + 71453 = 71472
29 + 71443 = 71472
43 + 71429 = 71472
53 + 71419 = 71472
59 + 71413 = 71472
61 + 71411 = 71472
73 + 71399 = 71472
83 + 71389 = 71472

Showing the first eight; more decompositions exist.
