Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8536, here are decompositions:
- 23 + 8513 = 8536
- 89 + 8447 = 8536
- 107 + 8429 = 8536
- 113 + 8423 = 8536
- 149 + 8387 = 8536
- 167 + 8369 = 8536
- 173 + 8363 = 8536
- 239 + 8297 = 8536
Showing the first eight; more decompositions exist.
