Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19476, here are decompositions:
- 5 + 19471 = 19476
- 7 + 19469 = 19476
- 13 + 19463 = 19476
- 19 + 19457 = 19476
- 29 + 19447 = 19476
- 43 + 19433 = 19476
- 47 + 19429 = 19476
- 53 + 19423 = 19476
Showing the first eight; more decompositions exist.
