Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704840, here are decompositions:
- 3 + 8704837 = 8704840
- 29 + 8704811 = 8704840
- 83 + 8704757 = 8704840
- 149 + 8704691 = 8704840
- 227 + 8704613 = 8704840
- 233 + 8704607 = 8704840
- 239 + 8704601 = 8704840
- 251 + 8704589 = 8704840
Showing the first eight; more decompositions exist.
