Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87182, here are decompositions:
- 3 + 87179 = 87182
- 31 + 87151 = 87182
- 61 + 87121 = 87182
- 79 + 87103 = 87182
- 223 + 86959 = 87182
- 313 + 86869 = 87182
- 331 + 86851 = 87182
- 439 + 86743 = 87182
Showing the first eight; more decompositions exist.
