Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722464, here are decompositions:
- 5 + 8722459 = 8722464
- 17 + 8722447 = 8722464
- 41 + 8722423 = 8722464
- 71 + 8722393 = 8722464
- 73 + 8722391 = 8722464
- 97 + 8722367 = 8722464
- 103 + 8722361 = 8722464
- 131 + 8722333 = 8722464
Showing the first eight; more decompositions exist.
