Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482664, here are decompositions:
- 23 + 31482641 = 31482664
- 47 + 31482617 = 31482664
- 113 + 31482551 = 31482664
- 263 + 31482401 = 31482664
- 383 + 31482281 = 31482664
- 491 + 31482173 = 31482664
- 617 + 31482047 = 31482664
- 683 + 31481981 = 31482664
Showing the first eight; more decompositions exist.
