Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187306, here are decompositions:
- 3 + 187303 = 187306
- 29 + 187277 = 187306
- 83 + 187223 = 187306
- 89 + 187217 = 187306
- 113 + 187193 = 187306
- 167 + 187139 = 187306
- 173 + 187133 = 187306
- 179 + 187127 = 187306
Showing the first eight; more decompositions exist.
