Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19832, here are decompositions:
- 13 + 19819 = 19832
- 19 + 19813 = 19832
- 31 + 19801 = 19832
- 73 + 19759 = 19832
- 79 + 19753 = 19832
- 151 + 19681 = 19832
- 223 + 19609 = 19832
- 229 + 19603 = 19832
Showing the first eight; more decompositions exist.
