Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47448, here are decompositions:
- 7 + 47441 = 47448
- 17 + 47431 = 47448
- 29 + 47419 = 47448
- 31 + 47417 = 47448
- 41 + 47407 = 47448
- 59 + 47389 = 47448
- 61 + 47387 = 47448
- 67 + 47381 = 47448
Showing the first eight; more decompositions exist.
