Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584622, here are decompositions:
- 5 + 31584617 = 31584622
- 71 + 31584551 = 31584622
- 191 + 31584431 = 31584622
- 233 + 31584389 = 31584622
- 239 + 31584383 = 31584622
- 359 + 31584263 = 31584622
- 389 + 31584233 = 31584622
- 431 + 31584191 = 31584622
Showing the first eight; more decompositions exist.
