Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989874, here are decompositions:
- 5 + 989869 = 989874
- 37 + 989837 = 989874
- 43 + 989831 = 989874
- 47 + 989827 = 989874
- 71 + 989803 = 989874
- 97 + 989777 = 989874
- 113 + 989761 = 989874
- 131 + 989743 = 989874
Showing the first eight; more decompositions exist.
