Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670028, here are decompositions:
- 47 + 8669981 = 8670028
- 89 + 8669939 = 8670028
- 131 + 8669897 = 8670028
- 149 + 8669879 = 8670028
- 167 + 8669861 = 8670028
- 197 + 8669831 = 8670028
- 251 + 8669777 = 8670028
- 359 + 8669669 = 8670028
Showing the first eight; more decompositions exist.
