Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155956, here are decompositions:
- 107 + 155849 = 155956
- 173 + 155783 = 155956
- 179 + 155777 = 155956
- 233 + 155723 = 155956
- 239 + 155717 = 155956
- 257 + 155699 = 155956
- 263 + 155693 = 155956
- 293 + 155663 = 155956
Showing the first eight; more decompositions exist.
