Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670420, here are decompositions:
- 13 + 8670407 = 8670420
- 23 + 8670397 = 8670420
- 47 + 8670373 = 8670420
- 67 + 8670353 = 8670420
- 89 + 8670331 = 8670420
- 107 + 8670313 = 8670420
- 139 + 8670281 = 8670420
- 163 + 8670257 = 8670420
Showing the first eight; more decompositions exist.
