Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65438, here are decompositions:
- 19 + 65419 = 65438
- 31 + 65407 = 65438
- 67 + 65371 = 65438
- 151 + 65287 = 65438
- 181 + 65257 = 65438
- 199 + 65239 = 65438
- 271 + 65167 = 65438
- 337 + 65101 = 65438
Showing the first eight; more decompositions exist.
