Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38780, here are decompositions:
- 13 + 38767 = 38780
- 31 + 38749 = 38780
- 43 + 38737 = 38780
- 67 + 38713 = 38780
- 73 + 38707 = 38780
- 103 + 38677 = 38780
- 109 + 38671 = 38780
- 127 + 38653 = 38780
Showing the first eight; more decompositions exist.
