Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31436, here are decompositions:
- 43 + 31393 = 31436
- 79 + 31357 = 31436
- 103 + 31333 = 31436
- 109 + 31327 = 31436
- 199 + 31237 = 31436
- 277 + 31159 = 31436
- 283 + 31153 = 31436
- 313 + 31123 = 31436
Showing the first eight; more decompositions exist.
