Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47400, here are decompositions:
- 11 + 47389 = 47400
- 13 + 47387 = 47400
- 19 + 47381 = 47400
- 37 + 47363 = 47400
- 47 + 47353 = 47400
- 61 + 47339 = 47400
- 83 + 47317 = 47400
- 97 + 47303 = 47400
Showing the first eight; more decompositions exist.
