Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64542, here are decompositions:
- 29 + 64513 = 64542
- 43 + 64499 = 64542
- 53 + 64489 = 64542
- 59 + 64483 = 64542
- 89 + 64453 = 64542
- 103 + 64439 = 64542
- 109 + 64433 = 64542
- 139 + 64403 = 64542
Showing the first eight; more decompositions exist.
