Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526884, here are decompositions:
- 3 + 31526881 = 31526884
- 5 + 31526879 = 31526884
- 107 + 31526777 = 31526884
- 113 + 31526771 = 31526884
- 131 + 31526753 = 31526884
- 251 + 31526633 = 31526884
- 281 + 31526603 = 31526884
- 461 + 31526423 = 31526884
Showing the first eight; more decompositions exist.
