Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 616, here are decompositions:
- 3 + 613 = 616
- 17 + 599 = 616
- 23 + 593 = 616
- 29 + 587 = 616
- 47 + 569 = 616
- 53 + 563 = 616
- 59 + 557 = 616
- 107 + 509 = 616
Showing the first eight; more decompositions exist.
