Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19746, here are decompositions:
- 7 + 19739 = 19746
- 19 + 19727 = 19746
- 29 + 19717 = 19746
- 37 + 19709 = 19746
- 47 + 19699 = 19746
- 59 + 19687 = 19746
- 137 + 19609 = 19746
- 149 + 19597 = 19746
Showing the first eight; more decompositions exist.
