Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1472, here are decompositions:

13 + 1459 = 1472
19 + 1453 = 1472
43 + 1429 = 1472
73 + 1399 = 1472
151 + 1321 = 1472
181 + 1291 = 1472
193 + 1279 = 1472
223 + 1249 = 1472

Showing the first eight; more decompositions exist.
