Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9974, here are decompositions:
- 7 + 9967 = 9974
- 43 + 9931 = 9974
- 67 + 9907 = 9974
- 73 + 9901 = 9974
- 103 + 9871 = 9974
- 157 + 9817 = 9974
- 163 + 9811 = 9974
- 193 + 9781 = 9974
Showing the first eight; more decompositions exist.
