Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79978, here are decompositions:
- 5 + 79973 = 79978
- 11 + 79967 = 79978
- 71 + 79907 = 79978
- 89 + 79889 = 79978
- 131 + 79847 = 79978
- 137 + 79841 = 79978
- 149 + 79829 = 79978
- 167 + 79811 = 79978
Showing the first eight; more decompositions exist.
