Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117780, here are decompositions:
- 7 + 117773 = 117780
- 17 + 117763 = 117780
- 23 + 117757 = 117780
- 29 + 117751 = 117780
- 53 + 117727 = 117780
- 59 + 117721 = 117780
- 71 + 117709 = 117780
- 79 + 117701 = 117780
Showing the first eight; more decompositions exist.
