Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87328, here are decompositions:
- 5 + 87323 = 87328
- 11 + 87317 = 87328
- 29 + 87299 = 87328
- 47 + 87281 = 87328
- 71 + 87257 = 87328
- 107 + 87221 = 87328
- 149 + 87179 = 87328
- 179 + 87149 = 87328
Showing the first eight; more decompositions exist.
