Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27930, here are decompositions:
- 11 + 27919 = 27930
- 13 + 27917 = 27930
- 29 + 27901 = 27930
- 37 + 27893 = 27930
- 47 + 27883 = 27930
- 79 + 27851 = 27930
- 83 + 27847 = 27930
- 103 + 27827 = 27930
Showing the first eight; more decompositions exist.
