Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115780, here are decompositions:
- 3 + 115777 = 115780
- 11 + 115769 = 115780
- 17 + 115763 = 115780
- 23 + 115757 = 115780
- 29 + 115751 = 115780
- 47 + 115733 = 115780
- 53 + 115727 = 115780
- 101 + 115679 = 115780
Showing the first eight; more decompositions exist.
