Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47648, here are decompositions:
- 19 + 47629 = 47648
- 67 + 47581 = 47648
- 79 + 47569 = 47648
- 127 + 47521 = 47648
- 151 + 47497 = 47648
- 157 + 47491 = 47648
- 229 + 47419 = 47648
- 241 + 47407 = 47648
Showing the first eight; more decompositions exist.
