Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75664, here are decompositions:
- 5 + 75659 = 75664
- 11 + 75653 = 75664
- 23 + 75641 = 75664
- 47 + 75617 = 75664
- 53 + 75611 = 75664
- 107 + 75557 = 75664
- 131 + 75533 = 75664
- 137 + 75527 = 75664
Showing the first eight; more decompositions exist.
