Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98870, here are decompositions:
- 3 + 98867 = 98870
- 61 + 98809 = 98870
- 97 + 98773 = 98870
- 139 + 98731 = 98870
- 157 + 98713 = 98870
- 181 + 98689 = 98870
- 229 + 98641 = 98870
- 307 + 98563 = 98870
Showing the first eight; more decompositions exist.
