Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1562, here are decompositions:
- 3 + 1559 = 1562
- 13 + 1549 = 1562
- 19 + 1543 = 1562
- 31 + 1531 = 1562
- 73 + 1489 = 1562
- 79 + 1483 = 1562
- 103 + 1459 = 1562
- 109 + 1453 = 1562
Showing the first eight; more decompositions exist.
