Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526818, here are decompositions:
- 41 + 31526777 = 31526818
- 47 + 31526771 = 31526818
- 149 + 31526669 = 31526818
- 431 + 31526387 = 31526818
- 467 + 31526351 = 31526818
- 677 + 31526141 = 31526818
- 761 + 31526057 = 31526818
- 797 + 31526021 = 31526818
Showing the first eight; more decompositions exist.
