Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127784, here are decompositions:
- 3 + 127781 = 127784
- 37 + 127747 = 127784
- 67 + 127717 = 127784
- 73 + 127711 = 127784
- 103 + 127681 = 127784
- 127 + 127657 = 127784
- 193 + 127591 = 127784
- 277 + 127507 = 127784
Showing the first eight; more decompositions exist.
