Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90178, here are decompositions:
- 5 + 90173 = 90178
- 29 + 90149 = 90178
- 71 + 90107 = 90178
- 89 + 90089 = 90178
- 107 + 90071 = 90178
- 167 + 90011 = 90178
- 239 + 89939 = 90178
- 269 + 89909 = 90178
Showing the first eight; more decompositions exist.
