Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47478, here are decompositions:
- 19 + 47459 = 47478
- 37 + 47441 = 47478
- 47 + 47431 = 47478
- 59 + 47419 = 47478
- 61 + 47417 = 47478
- 71 + 47407 = 47478
- 89 + 47389 = 47478
- 97 + 47381 = 47478
Showing the first eight; more decompositions exist.
