Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71616, here are decompositions:
- 19 + 71597 = 71616
- 23 + 71593 = 71616
- 47 + 71569 = 71616
- 53 + 71563 = 71616
- 67 + 71549 = 71616
- 79 + 71537 = 71616
- 89 + 71527 = 71616
- 113 + 71503 = 71616
Showing the first eight; more decompositions exist.
