Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22520, here are decompositions:
- 19 + 22501 = 22520
- 37 + 22483 = 22520
- 67 + 22453 = 22520
- 73 + 22447 = 22520
- 79 + 22441 = 22520
- 139 + 22381 = 22520
- 151 + 22369 = 22520
- 229 + 22291 = 22520
Showing the first eight; more decompositions exist.
