Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18374, here are decompositions:
- 3 + 18371 = 18374
- 7 + 18367 = 18374
- 61 + 18313 = 18374
- 67 + 18307 = 18374
- 73 + 18301 = 18374
- 151 + 18223 = 18374
- 157 + 18217 = 18374
- 163 + 18211 = 18374
Showing the first eight; more decompositions exist.
