Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37856, here are decompositions:
- 3 + 37853 = 37856
- 43 + 37813 = 37856
- 73 + 37783 = 37856
- 109 + 37747 = 37856
- 139 + 37717 = 37856
- 157 + 37699 = 37856
- 163 + 37693 = 37856
- 193 + 37663 = 37856
Showing the first eight; more decompositions exist.
