Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87550, here are decompositions:
- 3 + 87547 = 87550
- 11 + 87539 = 87550
- 41 + 87509 = 87550
- 59 + 87491 = 87550
- 107 + 87443 = 87550
- 167 + 87383 = 87550
- 191 + 87359 = 87550
- 227 + 87323 = 87550
Showing the first eight; more decompositions exist.
