Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19040, here are decompositions:
- 3 + 19037 = 19040
- 31 + 19009 = 19040
- 61 + 18979 = 19040
- 67 + 18973 = 19040
- 127 + 18913 = 19040
- 181 + 18859 = 19040
- 283 + 18757 = 19040
- 349 + 18691 = 19040
Showing the first eight; more decompositions exist.
