Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617436, here are decompositions:
- 5 + 31617431 = 31617436
- 23 + 31617413 = 31617436
- 29 + 31617407 = 31617436
- 107 + 31617329 = 31617436
- 167 + 31617269 = 31617436
- 197 + 31617239 = 31617436
- 269 + 31617167 = 31617436
- 359 + 31617077 = 31617436
Showing the first eight; more decompositions exist.
