Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64724, here are decompositions:
- 7 + 64717 = 64724
- 31 + 64693 = 64724
- 61 + 64663 = 64724
- 97 + 64627 = 64724
- 103 + 64621 = 64724
- 157 + 64567 = 64724
- 211 + 64513 = 64724
- 241 + 64483 = 64724
Showing the first eight; more decompositions exist.
