Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155860, here are decompositions:
- 11 + 155849 = 155860
- 59 + 155801 = 155860
- 83 + 155777 = 155860
- 113 + 155747 = 155860
- 137 + 155723 = 155860
- 167 + 155693 = 155860
- 197 + 155663 = 155860
- 233 + 155627 = 155860
Showing the first eight; more decompositions exist.
