Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64752, here are decompositions:
- 5 + 64747 = 64752
- 43 + 64709 = 64752
- 59 + 64693 = 64752
- 73 + 64679 = 64752
- 89 + 64663 = 64752
- 131 + 64621 = 64752
- 139 + 64613 = 64752
- 151 + 64601 = 64752
Showing the first eight; more decompositions exist.
