Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84200, here are decompositions:
- 19 + 84181 = 84200
- 37 + 84163 = 84200
- 73 + 84127 = 84200
- 79 + 84121 = 84200
- 139 + 84061 = 84200
- 331 + 83869 = 84200
- 367 + 83833 = 84200
- 409 + 83791 = 84200
Showing the first eight; more decompositions exist.
