Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164784, here are decompositions:
- 13 + 164771 = 164784
- 17 + 164767 = 164784
- 41 + 164743 = 164784
- 83 + 164701 = 164784
- 101 + 164683 = 164784
- 107 + 164677 = 164784
- 131 + 164653 = 164784
- 157 + 164627 = 164784
Showing the first eight; more decompositions exist.
