Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22530, here are decompositions:
- 19 + 22511 = 22530
- 29 + 22501 = 22530
- 47 + 22483 = 22530
- 61 + 22469 = 22530
- 83 + 22447 = 22530
- 89 + 22441 = 22530
- 97 + 22433 = 22530
- 139 + 22391 = 22530
Showing the first eight; more decompositions exist.
