Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158704, here are decompositions:
- 5 + 158699 = 158704
- 41 + 158663 = 158704
- 47 + 158657 = 158704
- 71 + 158633 = 158704
- 83 + 158621 = 158704
- 107 + 158597 = 158704
- 113 + 158591 = 158704
- 131 + 158573 = 158704
Showing the first eight; more decompositions exist.
