Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90198, here are decompositions:
- 7 + 90191 = 90198
- 11 + 90187 = 90198
- 71 + 90127 = 90198
- 109 + 90089 = 90198
- 127 + 90071 = 90198
- 131 + 90067 = 90198
- 139 + 90059 = 90198
- 167 + 90031 = 90198
Showing the first eight; more decompositions exist.
