Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38900, here are decompositions:
- 61 + 38839 = 38900
- 67 + 38833 = 38900
- 79 + 38821 = 38900
- 97 + 38803 = 38900
- 109 + 38791 = 38900
- 151 + 38749 = 38900
- 163 + 38737 = 38900
- 193 + 38707 = 38900
Showing the first eight; more decompositions exist.
