Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987474, here are decompositions:
- 11 + 987463 = 987474
- 17 + 987457 = 987474
- 41 + 987433 = 987474
- 83 + 987391 = 987474
- 113 + 987361 = 987474
- 181 + 987293 = 987474
- 223 + 987251 = 987474
- 263 + 987211 = 987474
Showing the first eight; more decompositions exist.
