Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64530, here are decompositions:
- 17 + 64513 = 64530
- 31 + 64499 = 64530
- 41 + 64489 = 64530
- 47 + 64483 = 64530
- 79 + 64451 = 64530
- 97 + 64433 = 64530
- 127 + 64403 = 64530
- 131 + 64399 = 64530
Showing the first eight; more decompositions exist.
