Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65570, here are decompositions:
- 7 + 65563 = 65570
- 13 + 65557 = 65570
- 19 + 65551 = 65570
- 31 + 65539 = 65570
- 73 + 65497 = 65570
- 151 + 65419 = 65570
- 157 + 65413 = 65570
- 163 + 65407 = 65570
Showing the first eight; more decompositions exist.
