Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1548, here are decompositions:
- 5 + 1543 = 1548
- 17 + 1531 = 1548
- 37 + 1511 = 1548
- 59 + 1489 = 1548
- 61 + 1487 = 1548
- 67 + 1481 = 1548
- 89 + 1459 = 1548
- 97 + 1451 = 1548
Showing the first eight; more decompositions exist.
