Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22470, here are decompositions:
- 17 + 22453 = 22470
- 23 + 22447 = 22470
- 29 + 22441 = 22470
- 37 + 22433 = 22470
- 61 + 22409 = 22470
- 73 + 22397 = 22470
- 79 + 22391 = 22470
- 89 + 22381 = 22470
Showing the first eight; more decompositions exist.
