Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90108, here are decompositions:
- 19 + 90089 = 90108
- 37 + 90071 = 90108
- 41 + 90067 = 90108
- 89 + 90019 = 90108
- 97 + 90011 = 90108
- 101 + 90007 = 90108
- 107 + 90001 = 90108
- 131 + 89977 = 90108
Showing the first eight; more decompositions exist.
