Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64784, here are decompositions:
- 3 + 64781 = 64784
- 37 + 64747 = 64784
- 67 + 64717 = 64784
- 151 + 64633 = 64784
- 157 + 64627 = 64784
- 163 + 64621 = 64784
- 193 + 64591 = 64784
- 271 + 64513 = 64784
Showing the first eight; more decompositions exist.
