Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78902, here are decompositions:
- 13 + 78889 = 78902
- 79 + 78823 = 78902
- 181 + 78721 = 78902
- 211 + 78691 = 78902
- 331 + 78571 = 78902
- 349 + 78553 = 78902
- 463 + 78439 = 78902
- 601 + 78301 = 78902
Showing the first eight; more decompositions exist.
