Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1532, here are decompositions:

43 + 1489 = 1532
61 + 1471 = 1532
73 + 1459 = 1532
79 + 1453 = 1532
103 + 1429 = 1532
109 + 1423 = 1532
151 + 1381 = 1532
211 + 1321 = 1532

Showing the first eight; more decompositions exist.
