Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87658, here are decompositions:
- 17 + 87641 = 87658
- 29 + 87629 = 87658
- 71 + 87587 = 87658
- 101 + 87557 = 87658
- 149 + 87509 = 87658
- 167 + 87491 = 87658
- 251 + 87407 = 87658
- 359 + 87299 = 87658
Showing the first eight; more decompositions exist.
