Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143744, here are decompositions:
- 67 + 143677 = 143744
- 127 + 143617 = 143744
- 151 + 143593 = 143744
- 193 + 143551 = 143744
- 241 + 143503 = 143744
- 277 + 143467 = 143744
- 283 + 143461 = 143744
- 331 + 143413 = 143744
Showing the first eight; more decompositions exist.
