Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65328, here are decompositions:
- 5 + 65323 = 65328
- 19 + 65309 = 65328
- 41 + 65287 = 65328
- 59 + 65269 = 65328
- 61 + 65267 = 65328
- 71 + 65257 = 65328
- 89 + 65239 = 65328
- 149 + 65179 = 65328
Showing the first eight; more decompositions exist.
