Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22472, here are decompositions:
- 3 + 22469 = 22472
- 19 + 22453 = 22472
- 31 + 22441 = 22472
- 103 + 22369 = 22472
- 181 + 22291 = 22472
- 193 + 22279 = 22472
- 199 + 22273 = 22472
- 283 + 22189 = 22472
Showing the first eight; more decompositions exist.
