Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64506, here are decompositions:
- 7 + 64499 = 64506
- 17 + 64489 = 64506
- 23 + 64483 = 64506
- 53 + 64453 = 64506
- 67 + 64439 = 64506
- 73 + 64433 = 64506
- 103 + 64403 = 64506
- 107 + 64399 = 64506
Showing the first eight; more decompositions exist.
