Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127684, here are decompositions:
- 3 + 127681 = 127684
- 5 + 127679 = 127684
- 41 + 127643 = 127684
- 47 + 127637 = 127684
- 83 + 127601 = 127684
- 101 + 127583 = 127684
- 191 + 127493 = 127684
- 197 + 127487 = 127684
Showing the first eight; more decompositions exist.
