Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5166, here are decompositions:
- 13 + 5153 = 5166
- 19 + 5147 = 5166
- 47 + 5119 = 5166
- 53 + 5113 = 5166
- 59 + 5107 = 5166
- 67 + 5099 = 5166
- 79 + 5087 = 5166
- 89 + 5077 = 5166
Showing the first eight; more decompositions exist.
