Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48900, here are decompositions:
- 11 + 48889 = 48900
- 17 + 48883 = 48900
- 29 + 48871 = 48900
- 31 + 48869 = 48900
- 41 + 48859 = 48900
- 43 + 48857 = 48900
- 53 + 48847 = 48900
- 79 + 48821 = 48900
Showing the first eight; more decompositions exist.
