Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87320, here are decompositions:
- 3 + 87317 = 87320
- 7 + 87313 = 87320
- 43 + 87277 = 87320
- 67 + 87253 = 87320
- 97 + 87223 = 87320
- 109 + 87211 = 87320
- 139 + 87181 = 87320
- 199 + 87121 = 87320
Showing the first eight; more decompositions exist.
