Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27440, here are decompositions:
- 3 + 27437 = 27440
- 13 + 27427 = 27440
- 31 + 27409 = 27440
- 43 + 27397 = 27440
- 73 + 27367 = 27440
- 79 + 27361 = 27440
- 103 + 27337 = 27440
- 157 + 27283 = 27440
Showing the first eight; more decompositions exist.
