Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38790, here are decompositions:
- 7 + 38783 = 38790
- 23 + 38767 = 38790
- 41 + 38749 = 38790
- 43 + 38747 = 38790
- 53 + 38737 = 38790
- 61 + 38729 = 38790
- 67 + 38723 = 38790
- 79 + 38711 = 38790
Showing the first eight; more decompositions exist.
