Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17742, here are decompositions:
- 5 + 17737 = 17742
- 13 + 17729 = 17742
- 29 + 17713 = 17742
- 59 + 17683 = 17742
- 61 + 17681 = 17742
- 73 + 17669 = 17742
- 83 + 17659 = 17742
- 163 + 17579 = 17742
Showing the first eight; more decompositions exist.
