Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187088, here are decompositions:
- 7 + 187081 = 187088
- 19 + 187069 = 187088
- 61 + 187027 = 187088
- 79 + 187009 = 187088
- 199 + 186889 = 187088
- 211 + 186877 = 187088
- 229 + 186859 = 187088
- 331 + 186757 = 187088
Showing the first eight; more decompositions exist.
