Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155932, here are decompositions:
- 11 + 155921 = 155932
- 41 + 155891 = 155932
- 71 + 155861 = 155932
- 83 + 155849 = 155932
- 131 + 155801 = 155932
- 149 + 155783 = 155932
- 191 + 155741 = 155932
- 233 + 155699 = 155932
Showing the first eight; more decompositions exist.
