Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722350, here are decompositions:
- 11 + 8722339 = 8722350
- 17 + 8722333 = 8722350
- 19 + 8722331 = 8722350
- 47 + 8722303 = 8722350
- 53 + 8722297 = 8722350
- 59 + 8722291 = 8722350
- 67 + 8722283 = 8722350
- 113 + 8722237 = 8722350
Showing the first eight; more decompositions exist.
