Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66426, here are decompositions:
- 13 + 66413 = 66426
- 23 + 66403 = 66426
- 43 + 66383 = 66426
- 53 + 66373 = 66426
- 67 + 66359 = 66426
- 79 + 66347 = 66426
- 83 + 66343 = 66426
- 89 + 66337 = 66426
Showing the first eight; more decompositions exist.
