Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70640, here are decompositions:
- 13 + 70627 = 70640
- 19 + 70621 = 70640
- 67 + 70573 = 70640
- 103 + 70537 = 70640
- 139 + 70501 = 70640
- 151 + 70489 = 70640
- 181 + 70459 = 70640
- 211 + 70429 = 70640
Showing the first eight; more decompositions exist.
