Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38864, here are decompositions:
- 3 + 38861 = 38864
- 13 + 38851 = 38864
- 31 + 38833 = 38864
- 43 + 38821 = 38864
- 61 + 38803 = 38864
- 73 + 38791 = 38864
- 97 + 38767 = 38864
- 127 + 38737 = 38864
Showing the first eight; more decompositions exist.
