Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722532, here are decompositions:
- 61 + 8722471 = 8722532
- 73 + 8722459 = 8722532
- 103 + 8722429 = 8722532
- 109 + 8722423 = 8722532
- 139 + 8722393 = 8722532
- 193 + 8722339 = 8722532
- 199 + 8722333 = 8722532
- 229 + 8722303 = 8722532
Showing the first eight; more decompositions exist.
