Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12850, here are decompositions:
- 29 + 12821 = 12850
- 41 + 12809 = 12850
- 59 + 12791 = 12850
- 107 + 12743 = 12850
- 137 + 12713 = 12850
- 179 + 12671 = 12850
- 191 + 12659 = 12850
- 197 + 12653 = 12850
Showing the first eight; more decompositions exist.
