Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11572, here are decompositions:
- 23 + 11549 = 11572
- 53 + 11519 = 11572
- 83 + 11489 = 11572
- 89 + 11483 = 11572
- 101 + 11471 = 11572
- 149 + 11423 = 11572
- 173 + 11399 = 11572
- 179 + 11393 = 11572
Showing the first eight; more decompositions exist.
