Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38388, here are decompositions:
- 11 + 38377 = 38388
- 17 + 38371 = 38388
- 37 + 38351 = 38388
- 59 + 38329 = 38388
- 61 + 38327 = 38388
- 67 + 38321 = 38388
- 71 + 38317 = 38388
- 89 + 38299 = 38388
Showing the first eight; more decompositions exist.
