Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989938, here are decompositions:
- 17 + 989921 = 989938
- 29 + 989909 = 989938
- 101 + 989837 = 989938
- 107 + 989831 = 989938
- 251 + 989687 = 989938
- 359 + 989579 = 989938
- 431 + 989507 = 989938
- 461 + 989477 = 989938
Showing the first eight; more decompositions exist.
