Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989740, here are decompositions:
- 53 + 989687 = 989740
- 179 + 989561 = 989740
- 233 + 989507 = 989740
- 263 + 989477 = 989740
- 317 + 989423 = 989740
- 359 + 989381 = 989740
- 419 + 989321 = 989740
- 431 + 989309 = 989740
Showing the first eight; more decompositions exist.
