Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22890, here are decompositions:
- 13 + 22877 = 22890
- 19 + 22871 = 22890
- 29 + 22861 = 22890
- 31 + 22859 = 22890
- 37 + 22853 = 22890
- 73 + 22817 = 22890
- 79 + 22811 = 22890
- 83 + 22807 = 22890
Showing the first eight; more decompositions exist.
