Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1470, here are decompositions:

11 + 1459 = 1470
17 + 1453 = 1470
19 + 1451 = 1470
23 + 1447 = 1470
31 + 1439 = 1470
37 + 1433 = 1470
41 + 1429 = 1470
43 + 1427 = 1470

Showing the first eight; more decompositions exist.
