Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27750, here are decompositions:
- 7 + 27743 = 27750
- 11 + 27739 = 27750
- 13 + 27737 = 27750
- 17 + 27733 = 27750
- 53 + 27697 = 27750
- 59 + 27691 = 27750
- 61 + 27689 = 27750
- 97 + 27653 = 27750
Showing the first eight; more decompositions exist.
