Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19474, here are decompositions:
- 3 + 19471 = 19474
- 5 + 19469 = 19474
- 11 + 19463 = 19474
- 17 + 19457 = 19474
- 41 + 19433 = 19474
- 47 + 19427 = 19474
- 53 + 19421 = 19474
- 71 + 19403 = 19474
Showing the first eight; more decompositions exist.
