Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65504, here are decompositions:
- 7 + 65497 = 65504
- 67 + 65437 = 65504
- 97 + 65407 = 65504
- 151 + 65353 = 65504
- 181 + 65323 = 65504
- 211 + 65293 = 65504
- 331 + 65173 = 65504
- 337 + 65167 = 65504
Showing the first eight; more decompositions exist.
