Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73920, here are decompositions:
- 13 + 73907 = 73920
- 23 + 73897 = 73920
- 37 + 73883 = 73920
- 43 + 73877 = 73920
- 53 + 73867 = 73920
- 61 + 73859 = 73920
- 71 + 73849 = 73920
- 73 + 73847 = 73920
Showing the first eight; more decompositions exist.
