Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51042, here are decompositions:
- 11 + 51031 = 51042
- 41 + 51001 = 51042
- 53 + 50989 = 51042
- 71 + 50971 = 51042
- 73 + 50969 = 51042
- 113 + 50929 = 51042
- 149 + 50893 = 51042
- 151 + 50891 = 51042
Showing the first eight; more decompositions exist.
