Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127272, here are decompositions:
- 11 + 127261 = 127272
- 23 + 127249 = 127272
- 31 + 127241 = 127272
- 53 + 127219 = 127272
- 83 + 127189 = 127272
- 109 + 127163 = 127272
- 139 + 127133 = 127272
- 149 + 127123 = 127272
Showing the first eight; more decompositions exist.
