Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147746, here are decompositions:
- 3 + 147743 = 147746
- 7 + 147739 = 147746
- 19 + 147727 = 147746
- 37 + 147709 = 147746
- 43 + 147703 = 147746
- 73 + 147673 = 147746
- 139 + 147607 = 147746
- 163 + 147583 = 147746
Showing the first eight; more decompositions exist.
