Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87966, here are decompositions:
- 5 + 87961 = 87966
- 7 + 87959 = 87966
- 23 + 87943 = 87966
- 79 + 87887 = 87966
- 89 + 87877 = 87966
- 97 + 87869 = 87966
- 113 + 87853 = 87966
- 163 + 87803 = 87966
Showing the first eight; more decompositions exist.
