Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47424, here are decompositions:
- 5 + 47419 = 47424
- 7 + 47417 = 47424
- 17 + 47407 = 47424
- 37 + 47387 = 47424
- 43 + 47381 = 47424
- 61 + 47363 = 47424
- 71 + 47353 = 47424
- 73 + 47351 = 47424
Showing the first eight; more decompositions exist.
