Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3278, here are decompositions:
- 7 + 3271 = 3278
- 19 + 3259 = 3278
- 61 + 3217 = 3278
- 97 + 3181 = 3278
- 109 + 3169 = 3278
- 157 + 3121 = 3278
- 199 + 3079 = 3278
- 211 + 3067 = 3278
Showing the first eight; more decompositions exist.
