Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526890, here are decompositions:
- 11 + 31526879 = 31526890
- 71 + 31526819 = 31526890
- 113 + 31526777 = 31526890
- 137 + 31526753 = 31526890
- 167 + 31526723 = 31526890
- 257 + 31526633 = 31526890
- 401 + 31526489 = 31526890
- 467 + 31526423 = 31526890
Showing the first eight; more decompositions exist.
