Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158644, here are decompositions:
- 11 + 158633 = 158644
- 23 + 158621 = 158644
- 47 + 158597 = 158644
- 53 + 158591 = 158644
- 71 + 158573 = 158644
- 107 + 158537 = 158644
- 137 + 158507 = 158644
- 251 + 158393 = 158644
Showing the first eight; more decompositions exist.
