Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 674, here are decompositions:
- 13 + 661 = 674
- 31 + 643 = 674
- 43 + 631 = 674
- 61 + 613 = 674
- 67 + 607 = 674
- 73 + 601 = 674
- 97 + 577 = 674
- 103 + 571 = 674
Showing the first eight; more decompositions exist.
