Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487746, here are decompositions:
- 5 + 487741 = 487746
- 13 + 487733 = 487746
- 19 + 487727 = 487746
- 29 + 487717 = 487746
- 37 + 487709 = 487746
- 43 + 487703 = 487746
- 89 + 487657 = 487746
- 97 + 487649 = 487746
Showing the first eight; more decompositions exist.
