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.
