Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19504, here are decompositions:
- 3 + 19501 = 19504
- 41 + 19463 = 19504
- 47 + 19457 = 19504
- 71 + 19433 = 19504
- 83 + 19421 = 19504
- 101 + 19403 = 19504
- 113 + 19391 = 19504
- 131 + 19373 = 19504
Showing the first eight; more decompositions exist.
