Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622, here are decompositions:
- 79 + 31543 = 31622
- 109 + 31513 = 31622
- 229 + 31393 = 31622
- 373 + 31249 = 31622
- 433 + 31189 = 31622
- 439 + 31183 = 31622
- 463 + 31159 = 31622
- 499 + 31123 = 31622
Showing the first eight; more decompositions exist.
