Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38518, here are decompositions:
- 17 + 38501 = 38518
- 59 + 38459 = 38518
- 71 + 38447 = 38518
- 167 + 38351 = 38518
- 191 + 38327 = 38518
- 197 + 38321 = 38518
- 257 + 38261 = 38518
- 281 + 38237 = 38518
Showing the first eight; more decompositions exist.
