Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3478, here are decompositions:
- 11 + 3467 = 3478
- 17 + 3461 = 3478
- 29 + 3449 = 3478
- 71 + 3407 = 3478
- 89 + 3389 = 3478
- 107 + 3371 = 3478
- 131 + 3347 = 3478
- 149 + 3329 = 3478
Showing the first eight; more decompositions exist.
