Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87622, here are decompositions:
- 83 + 87539 = 87622
- 113 + 87509 = 87622
- 131 + 87491 = 87622
- 149 + 87473 = 87622
- 179 + 87443 = 87622
- 239 + 87383 = 87622
- 263 + 87359 = 87622
- 401 + 87221 = 87622
Showing the first eight; more decompositions exist.
