Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40586, here are decompositions:
- 3 + 40583 = 40586
- 43 + 40543 = 40586
- 67 + 40519 = 40586
- 79 + 40507 = 40586
- 103 + 40483 = 40586
- 127 + 40459 = 40586
- 157 + 40429 = 40586
- 163 + 40423 = 40586
Showing the first eight; more decompositions exist.
