Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65450, here are decompositions:
- 3 + 65447 = 65450
- 13 + 65437 = 65450
- 31 + 65419 = 65450
- 37 + 65413 = 65450
- 43 + 65407 = 65450
- 79 + 65371 = 65450
- 97 + 65353 = 65450
- 127 + 65323 = 65450
Showing the first eight; more decompositions exist.
