Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87888, here are decompositions:
- 7 + 87881 = 87888
- 11 + 87877 = 87888
- 19 + 87869 = 87888
- 137 + 87751 = 87888
- 149 + 87739 = 87888
- 167 + 87721 = 87888
- 191 + 87697 = 87888
- 197 + 87691 = 87888
Showing the first eight; more decompositions exist.
