Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83570, here are decompositions:
- 7 + 83563 = 83570
- 13 + 83557 = 83570
- 73 + 83497 = 83570
- 127 + 83443 = 83570
- 139 + 83431 = 83570
- 163 + 83407 = 83570
- 181 + 83389 = 83570
- 229 + 83341 = 83570
Showing the first eight; more decompositions exist.
