Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188488, here are decompositions:
- 5 + 188483 = 188488
- 29 + 188459 = 188488
- 71 + 188417 = 188488
- 137 + 188351 = 188488
- 197 + 188291 = 188488
- 227 + 188261 = 188488
- 239 + 188249 = 188488
- 317 + 188171 = 188488
Showing the first eight; more decompositions exist.
