Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 974, here are decompositions:
- 3 + 971 = 974
- 7 + 967 = 974
- 37 + 937 = 974
- 67 + 907 = 974
- 97 + 877 = 974
- 151 + 823 = 974
- 163 + 811 = 974
- 223 + 751 = 974
Showing the first eight; more decompositions exist.
