Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22506, here are decompositions:
- 5 + 22501 = 22506
- 23 + 22483 = 22506
- 37 + 22469 = 22506
- 53 + 22453 = 22506
- 59 + 22447 = 22506
- 73 + 22433 = 22506
- 97 + 22409 = 22506
- 109 + 22397 = 22506
Showing the first eight; more decompositions exist.
