Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87392, here are decompositions:
- 79 + 87313 = 87392
- 139 + 87253 = 87392
- 181 + 87211 = 87392
- 211 + 87181 = 87392
- 241 + 87151 = 87392
- 271 + 87121 = 87392
- 379 + 87013 = 87392
- 433 + 86959 = 87392
Showing the first eight; more decompositions exist.
