Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7952, here are decompositions:
- 3 + 7949 = 7952
- 19 + 7933 = 7952
- 73 + 7879 = 7952
- 79 + 7873 = 7952
- 163 + 7789 = 7952
- 193 + 7759 = 7952
- 199 + 7753 = 7952
- 211 + 7741 = 7952
Showing the first eight; more decompositions exist.
