Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38128, here are decompositions:
- 59 + 38069 = 38128
- 89 + 38039 = 38128
- 131 + 37997 = 38128
- 137 + 37991 = 38128
- 239 + 37889 = 38128
- 257 + 37871 = 38128
- 281 + 37847 = 38128
- 317 + 37811 = 38128
Showing the first eight; more decompositions exist.
