Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127752, here are decompositions:
- 5 + 127747 = 127752
- 13 + 127739 = 127752
- 19 + 127733 = 127752
- 41 + 127711 = 127752
- 43 + 127709 = 127752
- 61 + 127691 = 127752
- 71 + 127681 = 127752
- 73 + 127679 = 127752
Showing the first eight; more decompositions exist.
