Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64500, here are decompositions:
- 11 + 64489 = 64500
- 17 + 64483 = 64500
- 47 + 64453 = 64500
- 61 + 64439 = 64500
- 67 + 64433 = 64500
- 97 + 64403 = 64500
- 101 + 64399 = 64500
- 127 + 64373 = 64500
Showing the first eight; more decompositions exist.
