Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717940, here are decompositions:
- 13 + 8717927 = 8717940
- 31 + 8717909 = 8717940
- 59 + 8717881 = 8717940
- 67 + 8717873 = 8717940
- 71 + 8717869 = 8717940
- 73 + 8717867 = 8717940
- 79 + 8717861 = 8717940
- 83 + 8717857 = 8717940
Showing the first eight; more decompositions exist.
