Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27420, here are decompositions:
- 11 + 27409 = 27420
- 13 + 27407 = 27420
- 23 + 27397 = 27420
- 53 + 27367 = 27420
- 59 + 27361 = 27420
- 83 + 27337 = 27420
- 137 + 27283 = 27420
- 139 + 27281 = 27420
Showing the first eight; more decompositions exist.
