Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40570, here are decompositions:
- 11 + 40559 = 40570
- 41 + 40529 = 40570
- 71 + 40499 = 40570
- 83 + 40487 = 40570
- 137 + 40433 = 40570
- 227 + 40343 = 40570
- 281 + 40289 = 40570
- 293 + 40277 = 40570
Showing the first eight; more decompositions exist.
