Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28056, here are decompositions:
- 5 + 28051 = 28056
- 29 + 28027 = 28056
- 37 + 28019 = 28056
- 59 + 27997 = 28056
- 73 + 27983 = 28056
- 89 + 27967 = 28056
- 103 + 27953 = 28056
- 109 + 27947 = 28056
Showing the first eight; more decompositions exist.
