Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13144, here are decompositions:
- 17 + 13127 = 13144
- 23 + 13121 = 13144
- 41 + 13103 = 13144
- 101 + 13043 = 13144
- 107 + 13037 = 13144
- 137 + 13007 = 13144
- 191 + 12953 = 13144
- 227 + 12917 = 13144
Showing the first eight; more decompositions exist.
