Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66456, here are decompositions:
- 7 + 66449 = 66456
- 43 + 66413 = 66456
- 53 + 66403 = 66456
- 73 + 66383 = 66456
- 79 + 66377 = 66456
- 83 + 66373 = 66456
- 97 + 66359 = 66456
- 109 + 66347 = 66456
Showing the first eight; more decompositions exist.
