Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27906, here are decompositions:
- 5 + 27901 = 27906
- 13 + 27893 = 27906
- 23 + 27883 = 27906
- 59 + 27847 = 27906
- 79 + 27827 = 27906
- 83 + 27823 = 27906
- 89 + 27817 = 27906
- 97 + 27809 = 27906
Showing the first eight; more decompositions exist.
