Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22878, here are decompositions:
- 7 + 22871 = 22878
- 17 + 22861 = 22878
- 19 + 22859 = 22878
- 61 + 22817 = 22878
- 67 + 22811 = 22878
- 71 + 22807 = 22878
- 101 + 22777 = 22878
- 109 + 22769 = 22878
Showing the first eight; more decompositions exist.
