Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27938, here are decompositions:
- 19 + 27919 = 27938
- 37 + 27901 = 27938
- 139 + 27799 = 27938
- 199 + 27739 = 27938
- 241 + 27697 = 27938
- 307 + 27631 = 27938
- 397 + 27541 = 27938
- 409 + 27529 = 27938
Showing the first eight; more decompositions exist.
