Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11780, here are decompositions:
- 3 + 11777 = 11780
- 37 + 11743 = 11780
- 61 + 11719 = 11780
- 79 + 11701 = 11780
- 103 + 11677 = 11780
- 163 + 11617 = 11780
- 193 + 11587 = 11780
- 229 + 11551 = 11780
Showing the first eight; more decompositions exist.
