Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77616, here are decompositions:
- 5 + 77611 = 77616
- 29 + 77587 = 77616
- 43 + 77573 = 77616
- 47 + 77569 = 77616
- 53 + 77563 = 77616
- 59 + 77557 = 77616
- 67 + 77549 = 77616
- 73 + 77543 = 77616
Showing the first eight; more decompositions exist.
