Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162580, here are decompositions:
- 3 + 162577 = 162580
- 17 + 162563 = 162580
- 23 + 162557 = 162580
- 53 + 162527 = 162580
- 107 + 162473 = 162580
- 167 + 162413 = 162580
- 191 + 162389 = 162580
- 293 + 162287 = 162580
Showing the first eight; more decompositions exist.
