Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42630, here are decompositions:
- 19 + 42611 = 42630
- 41 + 42589 = 42630
- 53 + 42577 = 42630
- 59 + 42571 = 42630
- 61 + 42569 = 42630
- 73 + 42557 = 42630
- 97 + 42533 = 42630
- 131 + 42499 = 42630
Showing the first eight; more decompositions exist.
