Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78502, here are decompositions:
- 5 + 78497 = 78502
- 23 + 78479 = 78502
- 101 + 78401 = 78502
- 191 + 78311 = 78502
- 269 + 78233 = 78502
- 311 + 78191 = 78502
- 401 + 78101 = 78502
- 443 + 78059 = 78502
Showing the first eight; more decompositions exist.
