Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65538, here are decompositions:
- 17 + 65521 = 65538
- 19 + 65519 = 65538
- 41 + 65497 = 65538
- 59 + 65479 = 65538
- 89 + 65449 = 65538
- 101 + 65437 = 65538
- 131 + 65407 = 65538
- 157 + 65381 = 65538
Showing the first eight; more decompositions exist.
