Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670742, here are decompositions:
- 29 + 8670713 = 8670742
- 89 + 8670653 = 8670742
- 131 + 8670611 = 8670742
- 191 + 8670551 = 8670742
- 233 + 8670509 = 8670742
- 239 + 8670503 = 8670742
- 251 + 8670491 = 8670742
- 389 + 8670353 = 8670742
Showing the first eight; more decompositions exist.
