Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38512, here are decompositions:
- 11 + 38501 = 38512
- 53 + 38459 = 38512
- 59 + 38453 = 38512
- 179 + 38333 = 38512
- 191 + 38321 = 38512
- 239 + 38273 = 38512
- 251 + 38261 = 38512
- 281 + 38231 = 38512
Showing the first eight; more decompositions exist.
