Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1598, here are decompositions:
- 19 + 1579 = 1598
- 31 + 1567 = 1598
- 67 + 1531 = 1598
- 109 + 1489 = 1598
- 127 + 1471 = 1598
- 139 + 1459 = 1598
- 151 + 1447 = 1598
- 199 + 1399 = 1598
Showing the first eight; more decompositions exist.
