Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155374, here are decompositions:
- 3 + 155371 = 155374
- 41 + 155333 = 155374
- 47 + 155327 = 155374
- 71 + 155303 = 155374
- 83 + 155291 = 155374
- 173 + 155201 = 155374
- 293 + 155081 = 155374
- 347 + 155027 = 155374
Showing the first eight; more decompositions exist.
