Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1552, here are decompositions:

3 + 1549 = 1552
29 + 1523 = 1552
41 + 1511 = 1552
53 + 1499 = 1552
59 + 1493 = 1552
71 + 1481 = 1552
101 + 1451 = 1552
113 + 1439 = 1552

Showing the first eight; more decompositions exist.
