Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87958, here are decompositions:
- 41 + 87917 = 87958
- 47 + 87911 = 87958
- 71 + 87887 = 87958
- 89 + 87869 = 87958
- 191 + 87767 = 87958
- 239 + 87719 = 87958
- 257 + 87701 = 87958
- 317 + 87641 = 87958
Showing the first eight; more decompositions exist.
