Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51738, here are decompositions:
- 17 + 51721 = 51738
- 19 + 51719 = 51738
- 47 + 51691 = 51738
- 59 + 51679 = 51738
- 79 + 51659 = 51738
- 101 + 51637 = 51738
- 107 + 51631 = 51738
- 131 + 51607 = 51738
Showing the first eight; more decompositions exist.
