Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27470, here are decompositions:
- 13 + 27457 = 27470
- 43 + 27427 = 27470
- 61 + 27409 = 27470
- 73 + 27397 = 27470
- 103 + 27367 = 27470
- 109 + 27361 = 27470
- 193 + 27277 = 27470
- 199 + 27271 = 27470
Showing the first eight; more decompositions exist.
