Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528818, here are decompositions:
- 5 + 31528813 = 31528818
- 7 + 31528811 = 31528818
- 11 + 31528807 = 31528818
- 17 + 31528801 = 31528818
- 67 + 31528751 = 31528818
- 89 + 31528729 = 31528818
- 149 + 31528669 = 31528818
- 197 + 31528621 = 31528818
Showing the first eight; more decompositions exist.
