Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670540, here are decompositions:
- 7 + 8670533 = 8670540
- 17 + 8670523 = 8670540
- 31 + 8670509 = 8670540
- 37 + 8670503 = 8670540
- 41 + 8670499 = 8670540
- 59 + 8670481 = 8670540
- 89 + 8670451 = 8670540
- 107 + 8670433 = 8670540
Showing the first eight; more decompositions exist.
