Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22820, here are decompositions:
- 3 + 22817 = 22820
- 13 + 22807 = 22820
- 37 + 22783 = 22820
- 43 + 22777 = 22820
- 79 + 22741 = 22820
- 103 + 22717 = 22820
- 151 + 22669 = 22820
- 181 + 22639 = 22820
Showing the first eight; more decompositions exist.
