Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8978, here are decompositions:
- 7 + 8971 = 8978
- 37 + 8941 = 8978
- 139 + 8839 = 8978
- 157 + 8821 = 8978
- 199 + 8779 = 8978
- 241 + 8737 = 8978
- 271 + 8707 = 8978
- 331 + 8647 = 8978
Showing the first eight; more decompositions exist.
