Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989120, here are decompositions:
- 61 + 989059 = 989120
- 109 + 989011 = 989120
- 157 + 988963 = 989120
- 211 + 988909 = 989120
- 271 + 988849 = 989120
- 283 + 988837 = 989120
- 331 + 988789 = 989120
- 337 + 988783 = 989120
Showing the first eight; more decompositions exist.
