Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87964, here are decompositions:
- 3 + 87961 = 87964
- 5 + 87959 = 87964
- 47 + 87917 = 87964
- 53 + 87911 = 87964
- 83 + 87881 = 87964
- 131 + 87833 = 87964
- 167 + 87797 = 87964
- 197 + 87767 = 87964
Showing the first eight; more decompositions exist.
