Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27442, here are decompositions:
- 5 + 27437 = 27442
- 11 + 27431 = 27442
- 113 + 27329 = 27442
- 251 + 27191 = 27442
- 263 + 27179 = 27442
- 383 + 27059 = 27442
- 431 + 27011 = 27442
- 449 + 26993 = 27442
Showing the first eight; more decompositions exist.
