Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38818, here are decompositions:
- 71 + 38747 = 38818
- 89 + 38729 = 38818
- 107 + 38711 = 38818
- 149 + 38669 = 38818
- 167 + 38651 = 38818
- 179 + 38639 = 38818
- 251 + 38567 = 38818
- 257 + 38561 = 38818
Showing the first eight; more decompositions exist.
