Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27738, here are decompositions:
- 5 + 27733 = 27738
- 37 + 27701 = 27738
- 41 + 27697 = 27738
- 47 + 27691 = 27738
- 107 + 27631 = 27738
- 127 + 27611 = 27738
- 157 + 27581 = 27738
- 197 + 27541 = 27738
Showing the first eight; more decompositions exist.
