Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535100, here are decompositions:
- 17 + 31535083 = 31535100
- 19 + 31535081 = 31535100
- 41 + 31535059 = 31535100
- 43 + 31535057 = 31535100
- 67 + 31535033 = 31535100
- 89 + 31535011 = 31535100
- 101 + 31534999 = 31535100
- 139 + 31534961 = 31535100
Showing the first eight; more decompositions exist.
