Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3128, here are decompositions:
- 7 + 3121 = 3128
- 19 + 3109 = 3128
- 61 + 3067 = 3128
- 67 + 3061 = 3128
- 79 + 3049 = 3128
- 109 + 3019 = 3128
- 127 + 3001 = 3128
- 157 + 2971 = 3128
Showing the first eight; more decompositions exist.
