Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 740, here are decompositions:
- 7 + 733 = 740
- 13 + 727 = 740
- 31 + 709 = 740
- 67 + 673 = 740
- 79 + 661 = 740
- 97 + 643 = 740
- 109 + 631 = 740
- 127 + 613 = 740
Showing the first eight; more decompositions exist.
