Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528854, here are decompositions:
- 11 + 31528843 = 31528854
- 13 + 31528841 = 31528854
- 23 + 31528831 = 31528854
- 31 + 31528823 = 31528854
- 41 + 31528813 = 31528854
- 43 + 31528811 = 31528854
- 47 + 31528807 = 31528854
- 53 + 31528801 = 31528854
Showing the first eight; more decompositions exist.
