Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87568, here are decompositions:
- 11 + 87557 = 87568
- 29 + 87539 = 87568
- 59 + 87509 = 87568
- 251 + 87317 = 87568
- 269 + 87299 = 87568
- 311 + 87257 = 87568
- 317 + 87251 = 87568
- 347 + 87221 = 87568
Showing the first eight; more decompositions exist.
