Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22830, here are decompositions:
- 13 + 22817 = 22830
- 19 + 22811 = 22830
- 23 + 22807 = 22830
- 43 + 22787 = 22830
- 47 + 22783 = 22830
- 53 + 22777 = 22830
- 61 + 22769 = 22830
- 79 + 22751 = 22830
Showing the first eight; more decompositions exist.
