Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38216, here are decompositions:
- 19 + 38197 = 38216
- 67 + 38149 = 38216
- 97 + 38119 = 38216
- 103 + 38113 = 38216
- 163 + 38053 = 38216
- 223 + 37993 = 38216
- 229 + 37987 = 38216
- 337 + 37879 = 38216
Showing the first eight; more decompositions exist.
