Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725320, here are decompositions:
- 13 + 8725307 = 8725320
- 41 + 8725279 = 8725320
- 67 + 8725253 = 8725320
- 101 + 8725219 = 8725320
- 103 + 8725217 = 8725320
- 113 + 8725207 = 8725320
- 137 + 8725183 = 8725320
- 167 + 8725153 = 8725320
Showing the first eight; more decompositions exist.
