Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1574, here are decompositions:
- 3 + 1571 = 1574
- 7 + 1567 = 1574
- 31 + 1543 = 1574
- 43 + 1531 = 1574
- 103 + 1471 = 1574
- 127 + 1447 = 1574
- 151 + 1423 = 1574
- 193 + 1381 = 1574
Showing the first eight; more decompositions exist.
