Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19892, here are decompositions:
- 3 + 19889 = 19892
- 31 + 19861 = 19892
- 73 + 19819 = 19892
- 79 + 19813 = 19892
- 139 + 19753 = 19892
- 193 + 19699 = 19892
- 211 + 19681 = 19892
- 283 + 19609 = 19892
Showing the first eight; more decompositions exist.
