Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87306, here are decompositions:
- 7 + 87299 = 87306
- 13 + 87293 = 87306
- 29 + 87277 = 87306
- 53 + 87253 = 87306
- 83 + 87223 = 87306
- 127 + 87179 = 87306
- 157 + 87149 = 87306
- 173 + 87133 = 87306
Showing the first eight; more decompositions exist.
