Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 924, here are decompositions:
- 5 + 919 = 924
- 13 + 911 = 924
- 17 + 907 = 924
- 37 + 887 = 924
- 41 + 883 = 924
- 43 + 881 = 924
- 47 + 877 = 924
- 61 + 863 = 924
Showing the first eight; more decompositions exist.
