Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538850, here are decompositions:
- 23 + 31538827 = 31538850
- 43 + 31538807 = 31538850
- 61 + 31538789 = 31538850
- 71 + 31538779 = 31538850
- 97 + 31538753 = 31538850
- 107 + 31538743 = 31538850
- 131 + 31538719 = 31538850
- 137 + 31538713 = 31538850
Showing the first eight; more decompositions exist.
