Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127772, here are decompositions:
- 61 + 127711 = 127772
- 103 + 127669 = 127772
- 109 + 127663 = 127772
- 163 + 127609 = 127772
- 181 + 127591 = 127772
- 193 + 127579 = 127772
- 223 + 127549 = 127772
- 349 + 127423 = 127772
Showing the first eight; more decompositions exist.
