Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538832, here are decompositions:
- 5 + 31538827 = 31538832
- 43 + 31538789 = 31538832
- 53 + 31538779 = 31538832
- 79 + 31538753 = 31538832
- 89 + 31538743 = 31538832
- 103 + 31538729 = 31538832
- 113 + 31538719 = 31538832
- 139 + 31538693 = 31538832
Showing the first eight; more decompositions exist.
