Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22990, here are decompositions:
- 17 + 22973 = 22990
- 29 + 22961 = 22990
- 47 + 22943 = 22990
- 53 + 22937 = 22990
- 83 + 22907 = 22990
- 89 + 22901 = 22990
- 113 + 22877 = 22990
- 131 + 22859 = 22990
Showing the first eight; more decompositions exist.
