Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2984, here are decompositions:
- 13 + 2971 = 2984
- 31 + 2953 = 2984
- 67 + 2917 = 2984
- 97 + 2887 = 2984
- 127 + 2857 = 2984
- 151 + 2833 = 2984
- 181 + 2803 = 2984
- 193 + 2791 = 2984
Showing the first eight; more decompositions exist.
