Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47992, here are decompositions:
- 11 + 47981 = 47992
- 23 + 47969 = 47992
- 29 + 47963 = 47992
- 41 + 47951 = 47992
- 53 + 47939 = 47992
- 59 + 47933 = 47992
- 89 + 47903 = 47992
- 149 + 47843 = 47992
Showing the first eight; more decompositions exist.
