Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36438, here are decompositions:
- 5 + 36433 = 36438
- 97 + 36341 = 36438
- 131 + 36307 = 36438
- 139 + 36299 = 36438
- 197 + 36241 = 36438
- 229 + 36209 = 36438
- 251 + 36187 = 36438
- 277 + 36161 = 36438
Showing the first eight; more decompositions exist.
