Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127738, here are decompositions:
- 5 + 127733 = 127738
- 11 + 127727 = 127738
- 29 + 127709 = 127738
- 47 + 127691 = 127738
- 59 + 127679 = 127738
- 89 + 127649 = 127738
- 101 + 127637 = 127738
- 131 + 127607 = 127738
Showing the first eight; more decompositions exist.
