Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188472, here are decompositions:
- 13 + 188459 = 188472
- 29 + 188443 = 188472
- 41 + 188431 = 188472
- 71 + 188401 = 188472
- 83 + 188389 = 188472
- 103 + 188369 = 188472
- 113 + 188359 = 188472
- 139 + 188333 = 188472
Showing the first eight; more decompositions exist.
