Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51012, here are decompositions:
- 11 + 51001 = 51012
- 19 + 50993 = 51012
- 23 + 50989 = 51012
- 41 + 50971 = 51012
- 43 + 50969 = 51012
- 61 + 50951 = 51012
- 83 + 50929 = 51012
- 89 + 50923 = 51012
Showing the first eight; more decompositions exist.
