Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27666, here are decompositions:
- 13 + 27653 = 27666
- 19 + 27647 = 27666
- 83 + 27583 = 27666
- 127 + 27539 = 27666
- 137 + 27529 = 27666
- 139 + 27527 = 27666
- 157 + 27509 = 27666
- 179 + 27487 = 27666
Showing the first eight; more decompositions exist.
