Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27678, here are decompositions:
- 5 + 27673 = 27678
- 31 + 27647 = 27678
- 47 + 27631 = 27678
- 61 + 27617 = 27678
- 67 + 27611 = 27678
- 97 + 27581 = 27678
- 127 + 27551 = 27678
- 137 + 27541 = 27678
Showing the first eight; more decompositions exist.
