Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723400, here are decompositions:
- 13 + 8723387 = 8723400
- 41 + 8723359 = 8723400
- 47 + 8723353 = 8723400
- 53 + 8723347 = 8723400
- 79 + 8723321 = 8723400
- 83 + 8723317 = 8723400
- 89 + 8723311 = 8723400
- 97 + 8723303 = 8723400
Showing the first eight; more decompositions exist.
