Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534842, here are decompositions:
- 11 + 31534831 = 31534842
- 23 + 31534819 = 31534842
- 41 + 31534801 = 31534842
- 43 + 31534799 = 31534842
- 89 + 31534753 = 31534842
- 103 + 31534739 = 31534842
- 113 + 31534729 = 31534842
- 151 + 31534691 = 31534842
Showing the first eight; more decompositions exist.
