Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187588, here are decompositions:
- 29 + 187559 = 187588
- 41 + 187547 = 187588
- 179 + 187409 = 187588
- 227 + 187361 = 187588
- 239 + 187349 = 187588
- 251 + 187337 = 187588
- 311 + 187277 = 187588
- 449 + 187139 = 187588
Showing the first eight; more decompositions exist.
