Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17388, here are decompositions:
- 5 + 17383 = 17388
- 11 + 17377 = 17388
- 29 + 17359 = 17388
- 37 + 17351 = 17388
- 47 + 17341 = 17388
- 61 + 17327 = 17388
- 67 + 17321 = 17388
- 71 + 17317 = 17388
Showing the first eight; more decompositions exist.
