Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87556, here are decompositions:
- 3 + 87553 = 87556
- 17 + 87539 = 87556
- 47 + 87509 = 87556
- 83 + 87473 = 87556
- 113 + 87443 = 87556
- 149 + 87407 = 87556
- 173 + 87383 = 87556
- 197 + 87359 = 87556
Showing the first eight; more decompositions exist.
