Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528908, here are decompositions:
- 67 + 31528841 = 31528908
- 97 + 31528811 = 31528908
- 101 + 31528807 = 31528908
- 107 + 31528801 = 31528908
- 157 + 31528751 = 31528908
- 167 + 31528741 = 31528908
- 179 + 31528729 = 31528908
- 211 + 31528697 = 31528908
Showing the first eight; more decompositions exist.
