Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38018, here are decompositions:
- 7 + 38011 = 38018
- 31 + 37987 = 38018
- 61 + 37957 = 38018
- 67 + 37951 = 38018
- 139 + 37879 = 38018
- 157 + 37861 = 38018
- 271 + 37747 = 38018
- 439 + 37579 = 38018
Showing the first eight; more decompositions exist.
