Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38178, here are decompositions:
- 11 + 38167 = 38178
- 29 + 38149 = 38178
- 59 + 38119 = 38178
- 109 + 38069 = 38178
- 131 + 38047 = 38178
- 139 + 38039 = 38178
- 167 + 38011 = 38178
- 181 + 37997 = 38178
Showing the first eight; more decompositions exist.
