Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51048, here are decompositions:
- 5 + 51043 = 51048
- 17 + 51031 = 51048
- 47 + 51001 = 51048
- 59 + 50989 = 51048
- 79 + 50969 = 51048
- 97 + 50951 = 51048
- 139 + 50909 = 51048
- 157 + 50891 = 51048
Showing the first eight; more decompositions exist.
