Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127444, here are decompositions:
- 41 + 127403 = 127444
- 71 + 127373 = 127444
- 101 + 127343 = 127444
- 113 + 127331 = 127444
- 167 + 127277 = 127444
- 173 + 127271 = 127444
- 197 + 127247 = 127444
- 227 + 127217 = 127444
Showing the first eight; more decompositions exist.
