Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51836, here are decompositions:
- 7 + 51829 = 51836
- 19 + 51817 = 51836
- 67 + 51769 = 51836
- 157 + 51679 = 51836
- 163 + 51673 = 51836
- 199 + 51637 = 51836
- 223 + 51613 = 51836
- 229 + 51607 = 51836
Showing the first eight; more decompositions exist.
