Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47472, here are decompositions:
- 13 + 47459 = 47472
- 31 + 47441 = 47472
- 41 + 47431 = 47472
- 53 + 47419 = 47472
- 83 + 47389 = 47472
- 109 + 47363 = 47472
- 163 + 47309 = 47472
- 179 + 47293 = 47472
Showing the first eight; more decompositions exist.
