Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548664, here are decompositions:
- 5 + 31548659 = 31548664
- 11 + 31548653 = 31548664
- 23 + 31548641 = 31548664
- 71 + 31548593 = 31548664
- 101 + 31548563 = 31548664
- 113 + 31548551 = 31548664
- 131 + 31548533 = 31548664
- 137 + 31548527 = 31548664
Showing the first eight; more decompositions exist.
