Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87906, here are decompositions:
- 19 + 87887 = 87906
- 29 + 87877 = 87906
- 37 + 87869 = 87906
- 53 + 87853 = 87906
- 73 + 87833 = 87906
- 103 + 87803 = 87906
- 109 + 87797 = 87906
- 113 + 87793 = 87906
Showing the first eight; more decompositions exist.
