Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1544, here are decompositions:
- 13 + 1531 = 1544
- 61 + 1483 = 1544
- 73 + 1471 = 1544
- 97 + 1447 = 1544
- 163 + 1381 = 1544
- 223 + 1321 = 1544
- 241 + 1303 = 1544
- 307 + 1237 = 1544
Showing the first eight; more decompositions exist.
