Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38840, here are decompositions:
- 7 + 38833 = 38840
- 19 + 38821 = 38840
- 37 + 38803 = 38840
- 73 + 38767 = 38840
- 103 + 38737 = 38840
- 127 + 38713 = 38840
- 163 + 38677 = 38840
- 211 + 38629 = 38840
Showing the first eight; more decompositions exist.
