Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38220, here are decompositions:
- 19 + 38201 = 38220
- 23 + 38197 = 38220
- 31 + 38189 = 38220
- 37 + 38183 = 38220
- 43 + 38177 = 38220
- 53 + 38167 = 38220
- 67 + 38153 = 38220
- 71 + 38149 = 38220
Showing the first eight; more decompositions exist.
