Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38020, here are decompositions:
- 23 + 37997 = 38020
- 29 + 37991 = 38020
- 53 + 37967 = 38020
- 113 + 37907 = 38020
- 131 + 37889 = 38020
- 149 + 37871 = 38020
- 167 + 37853 = 38020
- 173 + 37847 = 38020
Showing the first eight; more decompositions exist.
