Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8494, here are decompositions:
- 47 + 8447 = 8494
- 71 + 8423 = 8494
- 107 + 8387 = 8494
- 131 + 8363 = 8494
- 197 + 8297 = 8494
- 251 + 8243 = 8494
- 257 + 8237 = 8494
- 263 + 8231 = 8494
Showing the first eight; more decompositions exist.
