Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103888, here are decompositions:
- 47 + 103841 = 103888
- 101 + 103787 = 103888
- 269 + 103619 = 103888
- 311 + 103577 = 103888
- 359 + 103529 = 103888
- 431 + 103457 = 103888
- 467 + 103421 = 103888
- 479 + 103409 = 103888
Showing the first eight; more decompositions exist.
