Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87204, here are decompositions:
- 17 + 87187 = 87204
- 23 + 87181 = 87204
- 53 + 87151 = 87204
- 71 + 87133 = 87204
- 83 + 87121 = 87204
- 97 + 87107 = 87204
- 101 + 87103 = 87204
- 163 + 87041 = 87204
Showing the first eight; more decompositions exist.
