Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989556, here are decompositions:
- 23 + 989533 = 989556
- 79 + 989477 = 989556
- 89 + 989467 = 989556
- 137 + 989419 = 989556
- 179 + 989377 = 989556
- 229 + 989327 = 989556
- 233 + 989323 = 989556
- 263 + 989293 = 989556
Showing the first eight; more decompositions exist.
