Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51104, here are decompositions:
- 43 + 51061 = 51104
- 61 + 51043 = 51104
- 73 + 51031 = 51104
- 103 + 51001 = 51104
- 181 + 50923 = 51104
- 211 + 50893 = 51104
- 271 + 50833 = 51104
- 283 + 50821 = 51104
Showing the first eight; more decompositions exist.
