Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89478, here are decompositions:
- 19 + 89459 = 89478
- 29 + 89449 = 89478
- 47 + 89431 = 89478
- 61 + 89417 = 89478
- 79 + 89399 = 89478
- 97 + 89381 = 89478
- 107 + 89371 = 89478
- 149 + 89329 = 89478
Showing the first eight; more decompositions exist.
