Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7946, here are decompositions:
- 13 + 7933 = 7946
- 19 + 7927 = 7946
- 67 + 7879 = 7946
- 73 + 7873 = 7946
- 79 + 7867 = 7946
- 157 + 7789 = 7946
- 193 + 7753 = 7946
- 223 + 7723 = 7946
Showing the first eight; more decompositions exist.
