Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162564, here are decompositions:
- 7 + 162557 = 162564
- 11 + 162553 = 162564
- 37 + 162527 = 162564
- 41 + 162523 = 162564
- 47 + 162517 = 162564
- 71 + 162493 = 162564
- 107 + 162457 = 162564
- 113 + 162451 = 162564
Showing the first eight; more decompositions exist.
