Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51696, here are decompositions:
- 5 + 51691 = 51696
- 13 + 51683 = 51696
- 17 + 51679 = 51696
- 23 + 51673 = 51696
- 37 + 51659 = 51696
- 59 + 51637 = 51696
- 83 + 51613 = 51696
- 89 + 51607 = 51696
Showing the first eight; more decompositions exist.
