Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487668, here are decompositions:
- 11 + 487657 = 487668
- 17 + 487651 = 487668
- 19 + 487649 = 487668
- 31 + 487637 = 487668
- 61 + 487607 = 487668
- 67 + 487601 = 487668
- 79 + 487589 = 487668
- 107 + 487561 = 487668
Showing the first eight; more decompositions exist.
