Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71100, here are decompositions:
- 11 + 71089 = 71100
- 19 + 71081 = 71100
- 31 + 71069 = 71100
- 41 + 71059 = 71100
- 61 + 71039 = 71100
- 89 + 71011 = 71100
- 101 + 70999 = 71100
- 103 + 70997 = 71100
Showing the first eight; more decompositions exist.
