Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70490, here are decompositions:
- 3 + 70487 = 70490
- 31 + 70459 = 70490
- 61 + 70429 = 70490
- 67 + 70423 = 70490
- 97 + 70393 = 70490
- 109 + 70381 = 70490
- 139 + 70351 = 70490
- 163 + 70327 = 70490
Showing the first eight; more decompositions exist.
