Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87192, here are decompositions:
- 5 + 87187 = 87192
- 11 + 87181 = 87192
- 13 + 87179 = 87192
- 41 + 87151 = 87192
- 43 + 87149 = 87192
- 59 + 87133 = 87192
- 71 + 87121 = 87192
- 73 + 87119 = 87192
Showing the first eight; more decompositions exist.
