Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27438, here are decompositions:
- 7 + 27431 = 27438
- 11 + 27427 = 27438
- 29 + 27409 = 27438
- 31 + 27407 = 27438
- 41 + 27397 = 27438
- 71 + 27367 = 27438
- 101 + 27337 = 27438
- 109 + 27329 = 27438
Showing the first eight; more decompositions exist.
