Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47430, here are decompositions:
- 11 + 47419 = 47430
- 13 + 47417 = 47430
- 23 + 47407 = 47430
- 41 + 47389 = 47430
- 43 + 47387 = 47430
- 67 + 47363 = 47430
- 79 + 47351 = 47430
- 113 + 47317 = 47430
Showing the first eight; more decompositions exist.
