Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704458, here are decompositions:
- 41 + 8704417 = 8704458
- 89 + 8704369 = 8704458
- 107 + 8704351 = 8704458
- 127 + 8704331 = 8704458
- 149 + 8704309 = 8704458
- 179 + 8704279 = 8704458
- 229 + 8704229 = 8704458
- 239 + 8704219 = 8704458
Showing the first eight; more decompositions exist.
