Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28964, here are decompositions:
- 3 + 28961 = 28964
- 31 + 28933 = 28964
- 37 + 28927 = 28964
- 43 + 28921 = 28964
- 97 + 28867 = 28964
- 127 + 28837 = 28964
- 151 + 28813 = 28964
- 157 + 28807 = 28964
Showing the first eight; more decompositions exist.
