Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127288, here are decompositions:
- 11 + 127277 = 127288
- 17 + 127271 = 127288
- 41 + 127247 = 127288
- 47 + 127241 = 127288
- 71 + 127217 = 127288
- 131 + 127157 = 127288
- 149 + 127139 = 127288
- 251 + 127037 = 127288
Showing the first eight; more decompositions exist.
