Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8434, here are decompositions:
- 3 + 8431 = 8434
- 5 + 8429 = 8434
- 11 + 8423 = 8434
- 47 + 8387 = 8434
- 71 + 8363 = 8434
- 137 + 8297 = 8434
- 191 + 8243 = 8434
- 197 + 8237 = 8434
Showing the first eight; more decompositions exist.
