Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588, here are decompositions:
- 5 + 31583 = 31588
- 41 + 31547 = 31588
- 47 + 31541 = 31588
- 71 + 31517 = 31588
- 107 + 31481 = 31588
- 191 + 31397 = 31588
- 197 + 31391 = 31588
- 251 + 31337 = 31588
Showing the first eight; more decompositions exist.
