Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31356, here are decompositions:
- 19 + 31337 = 31356
- 23 + 31333 = 31356
- 29 + 31327 = 31356
- 37 + 31319 = 31356
- 79 + 31277 = 31356
- 89 + 31267 = 31356
- 97 + 31259 = 31356
- 103 + 31253 = 31356
Showing the first eight; more decompositions exist.
