Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7892, here are decompositions:
- 13 + 7879 = 7892
- 19 + 7873 = 7892
- 103 + 7789 = 7892
- 139 + 7753 = 7892
- 151 + 7741 = 7892
- 193 + 7699 = 7892
- 211 + 7681 = 7892
- 223 + 7669 = 7892
Showing the first eight; more decompositions exist.
