Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87936, here are decompositions:
- 5 + 87931 = 87936
- 19 + 87917 = 87936
- 59 + 87877 = 87936
- 67 + 87869 = 87936
- 83 + 87853 = 87936
- 103 + 87833 = 87936
- 139 + 87797 = 87936
- 193 + 87743 = 87936
Showing the first eight; more decompositions exist.
