Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1546, here are decompositions:
- 3 + 1543 = 1546
- 23 + 1523 = 1546
- 47 + 1499 = 1546
- 53 + 1493 = 1546
- 59 + 1487 = 1546
- 107 + 1439 = 1546
- 113 + 1433 = 1546
- 137 + 1409 = 1546
Showing the first eight; more decompositions exist.
