Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535148, here are decompositions:
- 5 + 31535143 = 31535148
- 17 + 31535131 = 31535148
- 41 + 31535107 = 31535148
- 67 + 31535081 = 31535148
- 89 + 31535059 = 31535148
- 137 + 31535011 = 31535148
- 149 + 31534999 = 31535148
- 167 + 31534981 = 31535148
Showing the first eight; more decompositions exist.
