Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149772, here are decompositions:
- 5 + 149767 = 149772
- 13 + 149759 = 149772
- 23 + 149749 = 149772
- 41 + 149731 = 149772
- 43 + 149729 = 149772
- 59 + 149713 = 149772
- 61 + 149711 = 149772
- 83 + 149689 = 149772
Showing the first eight; more decompositions exist.
