Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 132728, here are decompositions:
- 7 + 132721 = 132728
- 19 + 132709 = 132728
- 31 + 132697 = 132728
- 61 + 132667 = 132728
- 67 + 132661 = 132728
- 97 + 132631 = 132728
- 109 + 132619 = 132728
- 139 + 132589 = 132728
Showing the first eight; more decompositions exist.
