Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28064, here are decompositions:
- 7 + 28057 = 28064
- 13 + 28051 = 28064
- 37 + 28027 = 28064
- 67 + 27997 = 28064
- 97 + 27967 = 28064
- 103 + 27961 = 28064
- 163 + 27901 = 28064
- 181 + 27883 = 28064
Showing the first eight; more decompositions exist.
