Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27478, here are decompositions:
- 29 + 27449 = 27478
- 41 + 27437 = 27478
- 47 + 27431 = 27478
- 71 + 27407 = 27478
- 149 + 27329 = 27478
- 179 + 27299 = 27478
- 197 + 27281 = 27478
- 239 + 27239 = 27478
Showing the first eight; more decompositions exist.
