Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38420, here are decompositions:
- 43 + 38377 = 38420
- 103 + 38317 = 38420
- 139 + 38281 = 38420
- 181 + 38239 = 38420
- 223 + 38197 = 38420
- 271 + 38149 = 38420
- 307 + 38113 = 38420
- 337 + 38083 = 38420
Showing the first eight; more decompositions exist.
