Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38186, here are decompositions:
- 3 + 38183 = 38186
- 19 + 38167 = 38186
- 37 + 38149 = 38186
- 67 + 38119 = 38186
- 73 + 38113 = 38186
- 103 + 38083 = 38186
- 139 + 38047 = 38186
- 193 + 37993 = 38186
Showing the first eight; more decompositions exist.
