Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13742, here are decompositions:
- 13 + 13729 = 13742
- 19 + 13723 = 13742
- 31 + 13711 = 13742
- 61 + 13681 = 13742
- 73 + 13669 = 13742
- 109 + 13633 = 13742
- 151 + 13591 = 13742
- 229 + 13513 = 13742
Showing the first eight; more decompositions exist.
