Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74978, here are decompositions:
- 19 + 74959 = 74978
- 37 + 74941 = 74978
- 109 + 74869 = 74978
- 151 + 74827 = 74978
- 157 + 74821 = 74978
- 181 + 74797 = 74978
- 199 + 74779 = 74978
- 271 + 74707 = 74978
Showing the first eight; more decompositions exist.
