Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19002, here are decompositions:
- 23 + 18979 = 19002
- 29 + 18973 = 19002
- 43 + 18959 = 19002
- 83 + 18919 = 19002
- 89 + 18913 = 19002
- 103 + 18899 = 19002
- 163 + 18839 = 19002
- 199 + 18803 = 19002
Showing the first eight; more decompositions exist.
