Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19004, here are decompositions:
- 3 + 19001 = 19004
- 31 + 18973 = 19004
- 211 + 18793 = 19004
- 313 + 18691 = 19004
- 367 + 18637 = 19004
- 421 + 18583 = 19004
- 463 + 18541 = 19004
- 487 + 18517 = 19004
Showing the first eight; more decompositions exist.
