Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7862, here are decompositions:
- 73 + 7789 = 7862
- 103 + 7759 = 7862
- 109 + 7753 = 7862
- 139 + 7723 = 7862
- 163 + 7699 = 7862
- 181 + 7681 = 7862
- 193 + 7669 = 7862
- 223 + 7639 = 7862
Showing the first eight; more decompositions exist.
