Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187546, here are decompositions:
- 83 + 187463 = 187546
- 113 + 187433 = 187546
- 137 + 187409 = 187546
- 167 + 187379 = 187546
- 173 + 187373 = 187546
- 179 + 187367 = 187546
- 197 + 187349 = 187546
- 269 + 187277 = 187546
Showing the first eight; more decompositions exist.
