Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13244, here are decompositions:
- 3 + 13241 = 13244
- 61 + 13183 = 13244
- 67 + 13177 = 13244
- 73 + 13171 = 13244
- 97 + 13147 = 13244
- 151 + 13093 = 13244
- 181 + 13063 = 13244
- 211 + 13033 = 13244
Showing the first eight; more decompositions exist.
