Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700328, here are decompositions:
- 29 + 8700299 = 8700328
- 41 + 8700287 = 8700328
- 47 + 8700281 = 8700328
- 71 + 8700257 = 8700328
- 89 + 8700239 = 8700328
- 167 + 8700161 = 8700328
- 257 + 8700071 = 8700328
- 269 + 8700059 = 8700328
Showing the first eight; more decompositions exist.
